From the article there appears to be an arbitration path (based on the dollar amount quoted in the article, but they talk about it like it would be a lawsuit) - but Dad explicitly chose not to take it for some reason.
It would be very surprising if the ToS for Google Accounts didn't include an arbitration agreement.
Also, Dad had a paid Google One account - filled with apparently lots of data. He definitely has a legal path here and chose not to take it. Why?
