I would highly discourage using AI to translate things, especially if you mean to publish it.
That being said, I would also note, that ‘how do I translate a game’ is, unfortunately, not a generic question at all. Different games have different ways of packaging game data, including the language files. Even the same developer might change up how they store that data. I was translating the built-in Wii channels not long ago, and despite them all being first-party Nintendo titles made at roughly the same time, most of them used completely different methods of storing text, requiring me to make a new workflow after every channel for extracting and packaging the data for testing.
