A friend of mine studied theology and said (when I remarked something similar) that that's a very Protestant perspective.

Catholicism has had a long history of people disagreeing with the pope. There have been antipopes, wars between Catholics and the Papal State, theological factions where the Pope is just one participant, etc. . Papal infallibility is a very recent doctrine, and it only applies when he is speaking ex cathedra, which is rarely. Many Catholics don't adhere to it, and many only consider it a matter of worldly convenience against schisms.

That said, there are no AI generated images of Trump wearing Papal vestments or overseeing the holy mass. Trump is not presented as an anti-Pope, but as an anti-Christ.
