I use GrapheneOS ony phone and a Mac with the security options as optimized as possible. For most of my emailing etc, I use Tuta and Proton. There are instances however, where having a Google account is beneficial (some apps for example won’t download from Aurora store in anonymous mode).

Is it advisable/possible to create a dummy Google account with minimal ID/credentials? And if so, what are some best practices for doing so?

Or, do I resign myself to the fact that with more control over my data, I have to sacrifice more?
