How it is made should be irrelevant in the process. There is no way to stop people using LLM’s or other tools to create products like this report.
It should be globally a standard check to verify incoming documents and to determine their validity.
The interesting part on this case is that we see the real human aspect of it. Just asking for a report only finding the positive facts instead of doing real research.
That is an ethics question. When behaving like this (and it happened before LLM’s) it should be seen as an ethics violation. If not done there is no value in those legal procedures anymore.
The facts people have to accept is that the only place to check this is the deliverable. They are lucky now to have found the source, the prompts and the background but so many reports are entered without being so obvious.
It’s a terribly huge and complicated task.
