This is utterly wrong. The strength of LLMs is that they have very wide knowledge, so while your specialist knowledge might surpass them in a particular area it will know more than you across other topics. When brainstorming this wide knowledge is what you want. The trick is (as always) better prompting to push it hard - so things like "consider parallels in similar situations in other fields" are useful.
