Its hard to say because Pixel comes prepacked with a lot of models, not just ones that that are text output models.

With the caveat that I'm not on the pixel team and I'm not building _all_ the models that are on google's devices, its evident there are many models that support the Android experience. For example the one mentioned here

Yes of course, but I imagine there's only one main LLM on the device. Otherwise it's a waste of space to have multiple multi-gigabyte models that you then have to load into memory.
