Yup, there's a wonderful, presumably LLM generated, response to somebody explaining how trademark law actually works, the LLM response insists that explanation was all wrong and cites several US law cases. Most of the cases don't exist, the rest aren't about trademark law or anywhere close. But the LLM isn't supposed to say truths, it's a stochastic parrot, it makes what looks most plausible as a response. "Five" is a pretty plausible response to "What is two plus three?" but that's not because it added 2 + 3 = 5
