Output of `llm models` doesn't include openai models

[ackinc]

I'm running llm v0.28, with the anthropic plugin installed (among other plugins)

Running llm models returns the following output:

... while running llm openai models returns:

I was expecting the models listed in the output of llm openai models to also be included in the output of llm models, but they aren't. Is this a bug, or intended behaviour?
