Note that the above article is not just about attribution but also about inclusion of licenses with the copies of licensed code, something that, as far as I can tell, no LLM ever does. Is this because the code is so mashed together that it's impossible to say which bit was copied from which original source? Well, then, that's a very big problem and if a human did this we'd rightly label it plagiarism.
