fix(llm): Respect llm-server config flag to skip local server startup

When llm-server=false in bot_configuration, the code now skips
attempting to start local llama-server processes. This prevents
the 60-attempt timeout error when using external LLM endpoints
or when local LLM serving is intentionally disabled.
