Correct, it's not a country but an autonomous region belonging to Finland.
To make things not any easier, the only official language for Åland Islands is Swedish. The Swedish name is just Åland, nothing else. Nobody would call it Ålands öar, well a tourist brochure might call it Ålands örike (empire of islands) but that would sound ridiculous as an official name.
So basically Åland Islands can't be anything but an English name. Maybe not a very clean one because it contains a non-English letter. So Türkiye is not without precedence.
