I'm pretty sure the LLM services of the big general-purpose cloud providers do (I know for sure that Amazon Bedrock is a HIPAA Eligible Service, meaning it is covered within their standard Business Associate Addendum [their name for the Business Associate Agreeement as part of an AWS contract].)
Sorry to edit snipe you; I realized I hadn't checked in a while so I did a search and updated my comment. It appears OpenAI, Google, and Anthropic also offer BAAs for certain LLM services.
