It depends on the RAG use case. If the data and use case for the data is common enough, vendors could provide or put it behind a DVM. I have a few of these I'd like to launch, one for vector retrieval of Nostr notes. RAG can have a decent amount of parameters to tweak depending on the use case.

💯. This is a great reason for specialisation. The more tweaking required, the more resource intensive, and if it's not my core business, the more I would want to outsource it to your DVM.
