If a family member used LLM to write a letter to another, then at least the recipient can believe the sender feels the gratefulness in his/her human soul. If they used LLM to write a message in their own language, they would've proofread it to see if they agree with the sentiment, and "take ownership" of the message.

If it turns out the sender just told a machine to send their friends each a copy-pasted message, the sender is a lazy shallow asshole, but there's still in their heart an attempt of brightening someone's day, however lazily executed...
