> literally asking the LLM to translate an english phrase to german

I tried it a few times on arena.lmsys.org and given the prompt "Please translate "We thank you for your business" into German", the most common result was "Wir danken Ihnen für Ihr Geschäft", I got one bad result from some random tiny model and some more extensive responses from Gemini with suggestions for more idiomatic expressions. Modern LLMs are typically smart enough to understand this nuance when translating to German.
