feature(llm): managed using poetry

[returnToInnocence]

Background

Originally, we used pip to install modules by downloading and installing all the dependencies. pip does not manage this, but simply removes the module, leaving behind a bunch of dependencies that were installed when the module was downloaded and installed, which can cause conflicts when installing other libraries with this legacy and no longer useful library
