I personally don't know how to do it, but text-to-speech exists, such that you could scan or photograph (?) her paper and have it read to her by text-to-speech.
If she has diagnosed CI -- I think only vision can treat that. My son didn't and he could do OT instead -- which is frankly a lot more kid-friendly at least in our town. If she has CI though -- I think there is not a huge choice.
I think to some extent -- if you know she has CI and that right now may not be the right time to work on that, you can just HELP her directly with her work. Be like a tutor who teaches her. You don't HAVE to facilitate her homework, you don't have to facilitate the school expectations, if the school expectations are based on her reading, taking notes, etc., that aren't things she can do right now (but you are working on it in general -- you are going to get her the vision stuff when it is a better time). You can just help her with the content. If you don't have time or it is not going to work well, can you find a video for her to cover the content? Or can you find a book with pictures if that would help, that covers the content? Finding out what units/content are coming up and pre-teaching or pre-watching an appropriate movie or video can help SO MUCH going forward. If that is something you can ask the teacher, it can help so much, she can have more time for things to coalesce and maybe she will pick up more when there are visuals or a story (etc) instead of just reading from a textbook and listening to lectures.
In the longterm yes you want her to be able to outline etc, but in the meantime you don't have to do that to help her with content. And content goes a long way.
I think go ahead with your request, and make sure it is in writing. Make sure it is an official request, not a discussion where it is mentioned. They don't work the same way.
If you *know* she has CI -- I think you have got to accommodate on reading until you have had a good time to remediate that. You can accommodate with listening (if she does retain better than way) or by supplementing with other materials.
Another thing that I didn't do and then I did do ------- if it is At All possible, if you could take her out of school hours to do the CI stuff, it can go a long way. It lets them not end the day late and THEN have their things to get done. Can you take her later in the morning, or pick her up early in the afternoon?
I asked about this for speech therapy, and my son's teacher was concerned about him missing content for social studies, said that was a good time of school for him, etc. But doing speech therapy after school made his day so long.
Then when he did OT I took him out of school, and was a little more "I'm sorry, this is what needs to work out for my family," and it turned out to be so much better. We had some extenuating circumstances and logistics, but for him to be able to be done at the same time as school got out, and for us to have a bit of time just the two of us then (no siblings) worked out really good for us. If you work maybe there is someone you could ask or pay to take her, it is a thing. There is even private bus service some places, but it is usually not known about for kids who have minor issues. But if you asked maybe it turns out there is private bus service for kids who have more issues (and maybe can't attend regular after-school programs)..... you never know.
