So Attila was a pagan, I just got the idea he was an aethist from an inaccurate source on Roman history then. It is mentioned in history that he did meet with the pope. Well, the bad omen did not stop him from battling the Romans at Chalons. The only source I know of that labels Attila as an Atheist comes from the game series "Age of Empires". Things from these games are usually sensationalised merely for gameplay value. This source also made the meeting between Attila and Leo the main focus of his ceased assault on Italy. Of course, this too was likely oversensationalized. Even if the two actually did meet, it's doubtful that a pope would have any sway over a Hunnic warlord. As Asclepiades said, it was probably more of a PR stunt by the church to display its power to the people who were, at the time, very frightened.
