They certainly exist, but I don't think they are remotely as common. I can think of dozens of paid services that I use at work but one paid library. Maybe 5 if you include things like database SDKs where we paid for the database.
A lot of stuff in the automotive world has paid libraries. They can't be services because they need to be real-time, but they're not free because implementing a complex IEEE standard as software is not trivial.
