designated listener 

A person who may not understand what you're describing, but explaining a complex issue to them helps you better understand the problem, and therefore find a solution.

Although Jane does not know anything about machine learning she is happy to be John's designated listener when he describes the programming interface problems he is having with CHATGPT. In the process he was able to identify that he was using the wrong model/engine.
