Training data can't be the whole answer. LLMs are really good at translating to different programming languages. This makes sense, given that they are derived from text translation systems. I'm getting great results in languages with comparatively small bodies of freely available code. The bigger hurdle is usually that LLMs tend to copy common idioms in the target language and if it is an "enterprise-y" language like Java or C#, the amount of useless boilerplate can skyrocket immediately, which creates a real danger that the result grows beyond the usable context window size and the quality suffers.
