They are all artists though regardless. They are actually doing the work and doing the actual painting and require painting skills. What they are painting it itself or where they got the idea from is irrelevant. They painted it, as in the physical work and talent to achieve the result. In the case of AI Art, there is no point in the process where you are participating in the creation of the actual initial image unless the actual source/model is based of your own artwork that you created. What you are really doing with AI art is generating a concept based on a request you make (the prompt), and then modifying the result with other tools until you get what you want (inpainting masks, animate it, etc.). The equivalent of this would be something of like a patron/commissioner and something like a sound engineer. You aren't creating the source material, but you can ask an AI art generator to create something based on your request, and then modify and tune it afterwards to your liking. It is more of like a producer/sound engineer/post-production role.
