[Off topic: I was quite surprised to hear they were praying the

(Page 73. This shows the response in Italian, however it was done in the Greek= Kyrie eleison.)
Is this Litany a part of the Latin Church prayers? I assume the Mass itself, which I missed, was the Roman Rite. I’ve never heard
The Litany of Peace prayed in a Latin Church before. (We pray it at the start of every Divine Liturgy of St. John Chrysostom.)I don’t know. But, that was during the Procession itself, not in the Mass Proper, so I’m sure there is great flexibility in prayers and hymns used. Not to mention that the Byzantine Rite is part of the treasury of prayers of the Church and the Pope is fully right to make use of such – and it may even be well and good to use such in order to foster more unity in the Church.
