Ah okay, I didn't even know there was a way for me to find out how the Gnoll had been converted. Maybe I'm thinking of the wrong Gnoll or something, I haven't reached them in patch 5 yet and all I really remember about them in the previous playthrough I did was them being stupidly strong with lots of multiattacks, annoyingly always being on the high ground with their bows to make their multiattacks even stronger, and having weird ties to the Absolute and weird homebrew abilities and crap.
Follow up question though, why are the other Gnolls going along with this? Is it just like a strength, don't challenge the leader cause you'll be crushed kind of thing? Don't know too much about Gnoll lore, but wouldn't the others be kind of thrown off when their leader starts to follow some other god?
