As someone alluded to, the narrative that management drives has been examined and studied many times over. What is management saying, what are they not saying, what are they saying but not loudly, what did they say before that they no longer speak about. There are insights to glean but nothing that is giving you an unknown edge. Sentiment analysis and the like go back well into the late 80s, early 90s.

Tricking multiple LLMs with a certain poisonous combination of words and phrases sounds a lot like having a file that hashes to the same hash from different hashing techniques. Theoretically possible but actually practically impossible.
