[Feature]: Add embedded LiteLLM proxy option

[chkp-stevegi]

Confirmation

• This proposal is limited to ONE clearly defined enhancement.
• I understand this is a demo repository, not a production platform.

Problem Statement

Add subcomponent of LiteLLM to check for existing proxy and if not present, start it up so LiteLLM works OOTB without user setup

Proposed Solution

Create a LiteLLM subcomponent in this repo and add a config.yaml with all of the current available LLMs. This included Check Point's Azure Open AI models

Scope Boundaries

Don't add more than LiteLLM.

Demo Value

Make it much easier for people running Demo's with random LLMs to do so via LiteLLM

Estimated Complexity

Medium (new module or integration)
