I guess I don't understand what you mean when you say companies reselling said copyrighted artwork face no penalty. Why wouldn't they? If I was to make a copy of a Studio Ghibli movie and sell it, I would absolutely face a penalty if I was caught.
A common joke is to type in a description of some corporate IP and have ChatGPT generate it without ever saying it directly. Plenty of people have paid a subscription to do that, generate corporate IP that an artist could be sued over, but I don’t believe OpenAI has faced any legal issues if I’m correct, just as an example.
