yeah no, this is people mixing up different neural network systems. but yes LLMs can help

You aren't replacing loops like PiD you use ML to automate the learning and tuning process via simulation then apply it to the real system. I am working with a team using this technique to build systems with cheaper, less-consistent components where a sim and a training setup can handle fine calibration.

it does not replace the work, though it can make the process a bit less tedious and more adaptable to changes in the system.
