They do have some doodles that I don't think I can call AI but that doesn't mean the other art work isn't. As for the first image I don't really know. The shoulder cape seems to weirdly flow into itself and has a weird shadow. Idk what sort of AI would've even been available then but I do feel confident in saying they use it nowadays
Warning you all that the artist for this series, Ohnoru, is using AI. I first noticed in the other series they did "It Starts With Stalking" checked their twitter and the first image they posted is even AI
