Google has been pretty bad with released product names, e.g. YouTube Red, Google Wave, G Suite, Google Assistant, Google Home Hub... not very creative
There is no "Google" for these purposes. Every org has their own practices and there's minimal central review. GFoo is in vogue in some parts of the company, but you won't see that branding in YouTube, Chrome, Android, Fuschia, etc.
Unfortunately, they stopped doing this after Android 9 Pie (2018). All subsequent Android versions are just referred to by version number.
