You can programmatically enable automatic tracing of LLM calls to a supported LLM model like OpenAI or a framework like LangChain by setting `integrations_enabled` to `true` in the `LLMOBs.enable()` function. In addition to capturing latency and errors, the integrations capture the input parameters, input and output messages, and token usage (when available) of each traced call.
