I don't think that's possible in the current autocomplete based paradigm. But the LLM can be made to ignore most of its own knowledge. For example, Bing answers most questions by performing an Internet search, even if it could have answered without one. (Sometimes this makes it actually worse, e.g. when it is asked to solve a puzzle, and it gives answers to similar ones from the web, without trying to solve it itself.)
