There are multiple ways to defeat an inmortal being. After all, inmortality just means she can't die, not that she can't lose. They could just YEET her into outer space. Or send her to an alternate dimension. She won't die but she won't be a threat to Remnant anytime soon.

There's also the option of just taking away her inmortality. Taking the words of Bob, God of Light literally, she'll be able to die once she stops being a brat and learns to let it go and move on.
