It is most certainly built with a framework. It is just an internal framework.

Internal or external doesn't matter. The question is if it's used for more than one product - if not, then I'd argue it is not a framework.

And, yes, Google has internal JS frameworks, but I am not aware that GoogleDocs is based on one.
