Earlier quoted context omitted.
Cutting access in Europe does not solve anything. I'm living in US but I am European. Thus I can visit any of the above listed website they are processing my data, and GDPR applies to me. So they are not complying and I could file a complaint.
File a complaint with who ? There's no EU-wide data privacy regulator. Which specific EU country would have jurisdiction over an interaction which took place in the US?
OP’s country. The "place" that interaction took place in is irrelevant here, unless the company "doesn’t specifically target its services at individuals in the EU"; OP is citizen of an EU country so the GDPR rules apply.
