I think an LLM+Chroma is probably as good as it gets, and who knows, it might work. Just I'd be very careful of getting screwed by the process. As I'm sure you know LLMs are right at that inflection point where they're good enough to seem trustworthy but they can still completely malfunction (and they tend to do so in ways that are actually really difficult to spot because they seem perfectly plausible.)

Yeah the Legal Eagle video was hilarious. The guy used GPT-4 to make his legal briefs, then when it hallucinated cases he lied to the judge and said he'd researched them and the cases existed, then when faced with the clearly obvious fact that they didn't, he finally came clean but still sort of tried to weasel out of responsibility for the whole thing and the judge quite rightly tore him a new one. And, I have some vague memory of it being discovered that GPT had basically tried to tell him it wasn't qualified to make his legal briefs and he insisted to it that it needed to do it anyway. It was just an absolute casserole from start to finish.
