The difference if this is okay is how reliable the tool is. If it is a calculator or compiler it is okay. The example in the article also sounds okay (machine learning image classification), though I am not sure.

LLM output is unreliable, so we still need to judge it. If I want to be able to judge code, I must have worked with it to a certain extent. So the unreliable tool does not help me much if I don't want to accept the unreliability.
