If the product is the result of compiling all the open source code out in the wild into a LLM, it can be argued that the derived product, the LLM itself, must follow the licensing requirements of the used source code.

The AI companies don't care much about this. When the time comes, they will open their models or stop using sources that don't meet the appropriate licensing. Their current concern is learning how to build the best models, and win the race to become the dominant AI provider - who cares if they need to use polluted sources to reach their goal. They will fix it later.
