You are not a for profit software product. You are a human. If you make a drawing, that drawing MIGHT be a for profit product.

If I make a for profit AI, that AI is a product. And if that product required others' copyrighted works to derive it's deliverable, it is by definition creating derivative works. Again, creating a small human, not creating a product. Creating a for profit AI, creating a product.

If my product couldn't produce the same output without having at some point consumed the other works, I've triggered copyright concerns.

If I make and train a small human, I am not creating a for profit product so it doesn't come in to play at all. The two are not similar in any way. The human is not the product. If THEY create a product later (a drawing in this case) then THAT is where copyright comes in.
