It's a common confusion, but when you contract with Google Cloud, the service is provided by "Google Cloud EMEA Limited, Ireland", which is an European company, and when they provide you with a datacenter in Europe they are totally an European company operating in Europe.
This is different for example to DigitalOcean LLC, that is a US-entity providing service to European customers (this example has to be verified, but that's what I remember).
Google Cloud EMEA Limited, Ireland is subsidiary of US entity. It could just as well could be a US company with respect to privacy laws and regulations.
