Another thing is covers can be mistaken as AI for using similar art style. I showed a cover to Sailus for my newest novel, and he essentially said it was like AI. Even though it was actually paid for and made by a real artist...
I like pretty covers, so I tend to judge a book by its cover when buying. My thought process was that an author with an amazing cover must love their story in the same way, but as Ai-chan said, not all authors would have time/resource to get a hand drawn cover.
I believe you can still achieve something different. At the very least you can try doing a different pose. Even if AI shits itself, you can hide scuffed parts with title.
