I don't have any ideas to help you there. I was a TA in a university, but that was before ChatGPT, and it was an expectation to provide answers in English. For non-native English speakers, one of the big reasons to attend an English-speaking university was to get the experience in speaking and reading English.

But I also think it's a different thing entirely. It's different being the sole reader of text produced by your students (with responsibility to read the text) compared to being someone using the internet choosing what to read.
