so what if there were some numbers in the report which are in actuality, an order of magnitude or two outside of what you think is reasonable, because something was wrong, but the AI agent reports something that looks normal?

So as long as the LLM only makes errors in the single-digit percentage range, everything is peachy. Make number go up, but not by too much.

If you already know the report's numbers, why are you asking an LLM to generate it?

Usually because you need something vaguely technical and authoritative sounding to push for a decision you're already made.
