I learned a foreign language (English), I search Google in that foreign language. My browser's language is set in that foreign language. My search parameters are set to only show results in English. I use Google.com, not my localized version of Google. And yet about half the time when I search using keywords (as opposed to long expressions), there are always two or three links in my language (French) in the first page results.

Youtube is worse, I have two YT accounts in English where I only watch videos in English, and Youtube keeps recommending me videos in French that are not relevant at all to my interests (even though most recommendations in English are perfectly relevant). It's as if their AI just saw my IP and decided to recommend to me the most popular French videos of the moment.

A VPN is what you need. Or perhaps simply changing your location would work, when I visited France I didn’t get any French-language results.

What I needed was to use a different search engine. DuckDuckGo gives me a toggle to include or not French results.

ah! you had the solution all along!

Here's another tip. There are quiet, cheap, slow places you can go that don't require learning another language, or even going to another country. That's not what people really want though.
