THIS PR DOES NOT WORK IT WILL CRASH

Replaced by #60335 which is a rebase

Short example of using the llm-guard pip. Eventually I'll expand this to include calling it from a rails controller.

Adding llm_guard to existing pycdo package

Add deps to pycdo/pyproject.toml and install them

1. cd python/pycdo
2. Add the pip into pycdo/pyproject.toml: pdm add llm-guard
3. Back to the project root: cd ../..
4. Install the venv again: pdm install

Create python source

See changed files for details, but its just vanilla python at this point:

➜  pycdo git:(seth/pycall-llmguard-demo) find . | grep genai | grep py$
./pycdo/genai/__init__.py
./pycdo/genai/llmguard.py
./tests/genai/__init__.py
./tests/genai/test_llmguard.py

Now that we've added source, you can run python tests. From /python/pycdo run:

pdm run pytest

Or if you want to try using them from, say, ipython:

pdm run ipython

Alternative approach: create a new genai package

In this PR, I create llmguard.py inside the existing pycdo module, and add it to the deps for pycdo.

If genai (your name here) is going to use more python code than just a little llmguard, I suggest creating a new top-level genai package parallel to pycdo. Its not much harder, and I'm happy to help with this, but I just started here with the simplest possible example.
