The funny thing is that lawyers are themselves humans designed to say what their clients want to hear, or rather what their clients want the court to hear.
Give the same lawyer the same set of facts and ask them to present the case for the two opposing litigants, and they would come up with diametrically opposed interpretations of those facts, and entirely incompatible accounts of what case law must be followed, and what must be disregarded as irrelevant.
They should hardly be surprised when an LLM application does the same.
