Earlier quoted context omitted.
I see the same. I'm waiting on LLMs to get good enough that I can use them to help me learn foreign languages - e.g. talk to me about the news in language X. This way I can learn a language in an interesting and interactive way without burdening some poor human with my mistakes. I would build this myself but others will probably beat me too it.
I sometimes prompt the LLM to talk to me as a instructor - to suggest a topic, ask a question, read my response, correct my grammar, and suggest alternate vocabulary where appropriate. This works quite well. Similar to your comment, I am often hesitant to butcher a language in front of a real person :-).
These days, I do my best to learn and reflect. But any mistakes is just a reminder for more learning (and practice).
