But Starling has always been app only?

You can bank via the website here: https://app.starlingbank.com/login

Might be more limited than the app though.

Starling Bank has been officially supporting GrapheneOS using Android's hardware attestation API (not the Play Integrity API) since 2024.

It's not possible to login to the web-based banking without the app. It's a hard requirement to access the account.
