> Do you, as the website operator, have the right to copy and serve these fonts to your visitors?

All the fonts on Google Fonts are open source. When GDPR came into force in 2018 I downloaded all the fonts I needed, checked their licenses, and uploaded them on my servers along with necessary notices as required by the licenses.

The matter could also be sidestepped if the CDN were to offer a GDPR data processing agreement (DPA) and would make guarantees about the locations of servers. The free public CDNs understandably don't do this, and it seems Google Fonts is not covered by the Google Cloud DPA.
