Now I get where you are coming from (also not a lawyer):

- You asking the painter to create a Mickey Mouse painting: not illegal. You still are asking for a derivative work without permission, but if used privately you're good (this is different per jurisdiction) - The artist creating the painting of a derivative work is acting illegally - they are selling you the picture and hence this is a commercial act and trademark infringement - Displaying the bought Mickey Mouse image publicly is likely infringement, but worse is if you would charge admission to show the picture, that would definitely be illegal - If you were to hide the image in your basement and look at it privately, it would most likely not be illegal (private use - but see first point since this is different per jurisdiction)

Comparing violations doesn't really make sense (the artist creating it vs. you displaying it) - the act of creating the image for money is illegal. If it were the artist creating the image for him/herself - that would be fine.

Now getting back to the LLM and your question which also the court answered (jurisdiction: Germany). The courts opinion is that the AI recreating these lyrics by itself is illegal (think about the artist creating the image for you for money).

Personally I would think the key part and similarity is the payment. You pay for using OpenAI. You pay for it creating those lyrics/texts. In my head I can create a similar reasoning to your Mickey Mouse example. If we'd take open source LLMs and THEY would create perfect lyrics, I think the court would have a much harder case to make. Who would you be suing and for what kind of money? It would all be open source and nobody is paying anyone anything to recreate the lyrics. It would be and is very hard to prove that the LLMs were trained on copyrighted material - in the lyrics example, they may have ingested illegal lyrics-sharing sites, but they may also just have ingested Twitter or Reddit where people talk about the lyrics - how could any LLM know that these contents were illegal or not to be ingested.
