What good is research without the paper trail? I think it's necessary, just like writing user stories/specifications beforehand and e.g. merge request descriptions, but it's also a kind of toil that people would drag their heels on, slowing the whole process down.
Consider another area; a common heard complaint about why we don't see more police in the streets (where I live anyway, not the US) is that after every incident they have to spend time on doing paperwork - important administrative part of police work. Part of that work has been automated and outsourced, but not everything.
Of course, AI isn't perfect and can hallucinate things and get facts wrong which would impact a court case. But with the right guardrails, it can accellerate and partially automate this process even further.
