[FEATURE] Add Context for sensitive information and LLM sandboxing

[mbroecheler]

Is your feature request related to a problem? Please describe.
We don't want to expose sensitive API parameters (user ids, session ids, etc) to the LLM

Describe the solution you'd like
Sandbox the LLM so sensitive parameters aren't exposed and instead passed via context directly to the API

Describe alternatives you've considered
n/a

Additional context
