Correct. In order to get injunctive relief of having account access restored, you'd have to sue Google in a Superior Court.

The difference between Small Claims and Superior is that in the former you're generally not allowed to bring an attorney, whereas in the latter you may actually be required to bring one.

Does anyone know whether account suspension without a reason is actually something that a pro-se litigant has any chance of suing these big companies for, and winning at all?
