Fetch random town names based on countries

I've been struggling with this for a while now, and I've gotten somewhere between having it work once in a blue moon and completely breaking down.

My ultimate goal is to replace the "!R"s in the dictionary with a random town names from a region/country the user can chose from. Or for a concrete example, basically this kind of thing: https://www.mithrilandmages.com/utilities/CityNames.php

After starting to simply go online and copy-paste lists of town names into a .csv I realised that would take way to long and would be by far not exhaustive enough, and there are databases set up for this.

So I tried to get something working using GeoCoder and GeoNames...but I simply can't seem to make it work as I want it to work (or efficiently for that matter).

My current attempt was to just use children all the way down to the smallest child, but it's not very reliable and the queries take a while. Further, I can't seem to get something like United States work as a name. All the info I can find is to return specific longtitudes or IP addresses of specified locations, but that's far from what I'm looking for. I saw a library called "Faker", but I'm quite sure that's not what I'm looking for either, especially since I can't find any documentation on where its databases take their information from.

I'm just about ready to throw in the towel and try my hand at creating a RNG name generator that assembles words together.
