What this tells is the following:

1. You have absolutely no clue how the BitTorrent protocol works. 2. You have never maintained a widely used app as a single developer. 3. The extent of your use of LLMs is either academic / hobby or very narrowly focused and not integrated into a global product.

Just these points make your "suggestion" about using "LLMs to detect stuff is extremely easy" laughable at best.

The reason why people want to install their own software is to have freedom over their devices. The copyrighted content removal has a mechanism for it, called DMCA. And this is not how it works. The application does not have any content or means to circumvent any measures.
