Making LLMs more introspectable and explainable would be a huge win. But respecting licenses doesn't require going that far. 1) Restrict training to code under a specific documented set of acceptable licenses (permissive Open Source licenses). 2) Document the entire training set, and provide a file containing all the licenses and attributions. 3) People using code emitted by the LLM would then need to respect the union of all the licenses (e.g. MIT + BSD-2 + BSD-3 + Apache-2.0 + ...).
