That the story of Lot and Sodom and Gomorrah is mostly about in-hospitality and other sins comes from Scripture and is not a new interpretation:
Ezekiel 16: 1-2, 48-50: The word of the Lord came to me: 2 Mortal, make known to Jerusalem her abominations…48 As I live, says the Lord God,
your sister Sodom and her daughters have not done as you and your daughters have done. 49 This was the guilt of your sister Sodom: she and her daughters had pride, excess of food, and prosperous ease, but did not aid the poor and needy. 50 They were haughty, and did abominable things before me; therefore I removed them when I saw fit.
And if you object that Ezekiel 16:50 mentions “abominable things,” Ezekiel 16:21-22 makes clear that this is referring to sacrificing their children to other gods: 21 You slaughtered my children and delivered them up as an offering to them. 22 And in all your abominations and your whorings you did not remember the days of your youth, when you were naked and bare, flailing about in your blood.
Also, in Luke 10:1-2, 10-12: After this the Lord * appointed seventy others and sent them on ahead of him in pairs to every town and place where he himself intended to go 2 He said to them, ….10
But whenever you enter a town and they do not welcome you, go out into its streets and say, 11 ‘Even the dust of your town that clings to our feet, we wipe off in protest against you. Yet know this: the kingdom of God has come near.’ 12 I tell you, on that day it will be more tolerable for Sodom than for that town*.
Neither in Ezekiel or in Luke is homosexuality mentioned as the main sin of Sodom and Gomorrah.
Re: sexual immorality (ἐκπορνεύσασαι) and perversion (ἀπελθοῦσαι ὀπίσω σαρκὸς ἑτέρας – literally having departed to strange or different flesh.
Genesis 19 speaks plainly of the sin.
Ezekiel 16 retains the word abomination.
Jude 7 attests to sexual perversion as the central sin of Sodom and Gomorrah.
Leviticus 18:22
Do not lie with a man as one lies with a woman; it is an abomination.

CONGREGATION FOR THE DOCTRINE OF THE FAITH
LETTER TO THE BISHOPS OF THE CATHOLIC CHURCH
ON THE PASTORAL CARE OF HOMOSEXUAL PERSONS
6. Providing a basic plan for understanding this entire discussion of homosexuality is the theology of creation we find in Genesis. God, in his infinite wisdom and love, brings into existence all of reality as a reflection of his goodness. He fashions mankind, male and female, in his own image and likeness. Human beings, therefore, are nothing less than the work of God himself; and in the complementarity of the sexes, they are called to reflect the inner unity of the Creator. They do this in a striking way in their cooperation with him in the transmission of life by a mutual donation of the self to the other.
In Genesis 3, we find that this truth about persons being an image of God has been obscured by original sin. There inevitably follows a loss of awareness of the covenantal character of the union these persons had with God and with each other. The human body retains its “spousal significance” but this is now clouded by sin. Thus, in Genesis 19:1-11, the deterioration due to sin continues in the story of the men of Sodom. There can be no doubt of the moral judgement made there against homosexual relations. In Leviticus 18:22 and 20:13, in the course of describing the conditions necessary for belonging to the Chosen People, the author excludes from the People of God those who behave in a homosexual fashion.
Against the background of this exposition of theocratic law, an eschatological perspective is developed by St. Paul when, in I Cor 6:9, he proposes the same doctrine and lists those who behave in a homosexual fashion among those who shall not enter the Kingdom of God.
In Romans 1:18-32, still building on the moral traditions of his forebears, but in the new context of the confrontation between Christianity and the pagan society of his day, Paul uses homosexual behaviour as an example of the blindness which has overcome humankind. Instead of the original harmony between Creator and creatures, the acute distortion of idolatry has led to all kinds of moral excess. Paul is at a loss to find a clearer example of this disharmony than homosexual relations. Finally, 1 Tim. 1, in full continuity with the Biblical position, singles out those who spread wrong doctrine and in v. 10 explicitly names as sinners those who engage in homosexual acts.
