you can copyright a specific implementation but that doesn't necessarily grant a patent on the "algorithm". so unless darling is patented then a translation of the "algorithms" in darling is legal. to wit: that's why all the "numerical recipes" books couldn't block implementations in other languages.
IANAL and I don't think you are either. Be careful making simplistic inferences about a complicated system. Human "translation" is one thing, algorithmic "translation" has seen separate treatment in IP case law.[1] Whether this has relevance to LLM transformation or recall I don't know.

Do you understand what you're saying?
> Human "translation" is one thing
No it's not since "human translation" is literally all we had until about a year ago.
You should read the case again because it doesn't say what you think it says - it says generating a copyrighted work via a new system is still infringement (which is exactly what I'm arguing isn't happening in this case because what's being generated is a new language impl).
To put it very simply: if I use a machine (biological or electrical) to translate my favorite song into another language that's not infringement.
