@LukeAlmighty I don't think it's laziness. A lot of games come in a shit ton of languages already. Czech is a pretty niche language, so it's more like it's not worth the trouble. English, Chinese, Spanish, French, Italian, Portuguese, German, Russian are usually the big ones, sometimes you get some others thrown in there like Ukrainian, Polish, Brazilian Portuguese, or Japanese. Especially lately.

Game devs don't know how to properly deliver and compress all of this though so it really bloats the file size. It is very common for repacks to omit them unless you want them to make the file size smaller.

Part of it is just that so many people in your country speak other, more popular languages as well. You're not going to find many games translated even to something like Swedish because a lot of those people either speak German or English too, at least enough to play the game. It's not just about paying Czech voice actors or something but also hiring translators, audio production staff that understands the language, not to mention the extra work that needs to happen which will extend development time.

I wouldn't use any type of automated translation for my games honestly, because the truth is that I wouldn't know exactly what was being conveyed and I don't want that low quality association. That's something that modders should have the ability to do though for sure, you expect a lot more rough edges from a mod.
