> if you just followed the simple license

But there's the rub. If you found the code on Github, you would have seen the "simple licence" which required you to either give an attribution, release your code under a specific licence, seek an alternative licence, or perform some other appropriate action.

But if the LLM generates the code for you, you don't know the conditions of the "simple license" in order to follow them. So you are probably violating the conditions of the original license, but because someone can try to say "I didn't copy that code, I just generated some new code using an LLM", they try to ignore the fact that it's based on some other code in a Github somewhere.
