Under certain circumstances, Google does offer the option to have all domain level emails/data stored on US servers... meaning that any data related to a particular domain is only stored on servers within the US, and will not replicate to server outside the US.
I've seen this deployed first-hand with new Google Domains that require data be stored within the US, such as for Government or Military related contracts/vendors/subsidiarities.
