That sounds to me less of an issue with ChatGPT, and more with having colleagues that don't understand how to engage in reasonable discussion or evaluate information correctly.
I think my default response would be (regardless of the ChatGPT instructions):
"I looked it over and it doesn't actually work. ChatGPT is good for many high level things but when the specifics get technical, is struggles and invents solutions that don't exist; like a bloom filter. Ask ChaGPT what a bloom filter is."
