Integrating Phoenix for LLM Usage on Ollama and Amazon Bedrock

I want to use Phoenix to instrument usage of LLMs running on both (a) Ollama locally, and (b) on Amazon Bedrock. These models would be accessed from various sources, for example: using Open WebUI. Is there a way to wire in Phoenix to the LLM-side? I ask because I won't have access to all of the clients using these models.
