There are many VPN providers Vivaldi could have teamed up with, but it is unfortunate, that the web browser that's splash screen reads, "Made with love in Europe" picked a company that falls under Us Jurisdiction, and whose CEO praises Donald Trump.

Your company can start in another country, but if you expand into the United States, it falls under Us Jurisdiction. Our laws are very predatorial and assiduous.
There are 200 or so independent countries, territories, and states world-wide. But as you know, corporations do not include terms and conditions for all 200 or so geographical jurisdictions. Businesses only include and worry about the jurisdictions that apply to them.
That said, I would much rather let their own legal documentation speak for itself. Here are their terms concerning Proton. It has whole sections concerning US Customers and US Laws. https://proton.me/wallet/terms A company outside Us Law would not care about American laws, anymore than you would likely care about the law in North Korea, for example.
Proton would like to argue, likely from a public relations standing point, that these terms only apply to Proton Wallet. But that is not how our laws work in the United States. You do not get to pick and choose which department is subject to US Law, anymore than you get to pick which Us Laws you want to follow.
