I took a look, it's just a matter of a getting the scripts out of the script.arc archive, translating them and then repacking them, so it's terribly easy.
Using AI could work but not without extra guard rails to be sure it didn't mess with the scripting. But if you wish to go that route, it might be easier and faster to just use some tool to translate at runtime. I don't really use Textractor and the like anymore, I'm sure there must be better alternative nowadays.
