Since a lie is intrinsically evil, a person’s intent upon speaking does not mitigate evil. It is the material of the act, the act itself, and neither intent nor circumstance which define the act as evil.
Lack of intent to profit from one’s actions, whether this ever truly happens or not, does not make a lie any less a sin. The question is whether the sin is light or grave, not whether it is sin at all.

I think the confusion comes because we are using the colloquial definition of a lie interchangeably with the definition of a lie in the Catechism, as if these are the same thing. As it turns out, they are not.
The Church teaches that lying is an intrinsic evil, BUT the Church specifically does not teach that every untrue statement made with an intent to deceive is a lie!
2483 Lying is the most direct offense against the truth. To lie is to speak or act against the truth in order to lead into error someone who has the right to know the truth. By injuring man’s relation to truth and to his neighbor, a lie offends against the fundamental relation of man and of his word to the Lord.
Note the qualification in the Catechism. If you are speaking or acting against the truth, the act does not meet the Church’s definition of a lie
unless you are leading into error someone who has the right to know the truth. Webster’s dictionary uses the broader definition, which makes any untrue statement made with an intent to deceive or any creation of a false or misleading impression into a lie.
If the Church really meant that there was no time in which intentionally leading someone into error was not a lie, which is what you are implying, then the Church would teach “To lie is to speak or act against the truth in order to lead someone into error”, but that is not how the Church defines the meaning of a lie.
Rather, in her Catechism, the Church specifically
narrows the definition of lying to exclude speech or action against the truth that leads into error someone who does not have the right to know the truth.
On that account, if the Pope were to have directed someone to lead another person into error when the other person being deceived had no right to know the truth he or she was seeking, the Pope would not be encouraging someone to lie at all. So, while there is disagreement over whether false baptismal certificates were generated with knowledge of Pope Pius XII, certainly if the sisters in Rome who were hiding Jewish men in their convents (this
is a fact) lead the Nazis into error about that, the sisters would not be committing the sin of lying. It wouldn’t even be a venial sin, not a sin at all.
Therefore: It is not lying for police to deceive people suspected of crimes, it is not lying for people in the military to provide false information to those who have no right to the truth, it is not a lie for one of us to provide false information to a robber who wants to know if we have money or a murderer who asks us if we are alone in the house. It is not even a lie to raise your eyebrows to imply that your poker hand is better than it is.
If the person has no right to the information they seek, it is no lie to speak or act so as to mislead them.
