some people like myself aren't very detail oriented especially when you have around a hundred other bookmarked things you tend not to notice small changes in the art style unless you're bingeing it

Honestly, I reread the chapter and it was mostly the way the demon cult leader guy looked. Other than the details like the water on him seeming a bit off, the lighting seemed really similar to Youngest Scion Of The Mages at times, which is known to use ai art. Also, face shapes were inconsistent between characters, and the facial expressions sometimes looked off. I get that a lot of these things could just be because of a new artist being bad, but again, comparing it to both ai images I've seen in general and that specific manhwa, it looks like this is either partly ai-generated or at least ai-assisted

I don't know ether. But i know that there's AI art in the Leon lionheart Hunter manhwa (sorry i forgot the series name)
