Their translation service is based on llms and is commercially a successful product.
Also, LLMs use "in-context learning" ie you actually ask it "hey, translate this" and then it has a conversation with you where you can ask to clarify or provide word definitions.
Google Translate is more hardcoded; a big problem with it is that it can't explain any of the decisions it's made or show its uncertainty about anything.
Of course, neither of these are reliable since they hallucinate.
