ai-assisted art is not banned. In addition, Misaka has produced staggeringly high-quality lewd art for a long time. For that reason, I'm inclined to believe that if their work looks ai-generated, it's because the algorithms have been heavily trained on their work.

This seems ai-assisted, judging by the string of saliva connecting to nothing, weird feathers/fur on the right side of the image near her arm, weird arm grasping her thigh (thumbs do not look like that). If someone feels strongly about it and trusts their judgement, they can add the ai-assisted tag.
