He probably meant _brainwashed_ LLMs. They can consistently produce desired results if you wash them the right way. It's more about personal opinion than computation. Actually it would be fun to manipulate verdicts with prompt injections ;)
With the caveat that this applies to sane legal systems, and not the ones where "making examples" etc are part of the system.
hmm.. :) I like this. But the reality is very different and some factors which shouldn't matter can change the outcome dramatically. Like skin colors of defendant and judge. Pointing this out can be punished as well.
