Just wanna start off by saying that with young unformed minds, it does probably harm more on average than it helps. But particularly for spelling and reading, it might maybe actually help?
To be efficient with AI and LLMs you need to be good at least two things, reading and writing. One easy way of getting better is by reading a lot, and writing a lot. Maybe if we coax the kids into understanding (believing?) that better reading and writing helps them use AI better, they'd pay more attention to it?
No, you can talk to them, and have them talk back. And it's really easy. You don't need to be good at reading or writing to use it.
You mean you can place transcript/dictation in front of them, so you don't have to type your words but you can speak them, and the LLM will receive text? If so I'd still argue it's important to be able to read and write to be able to use them effectively, but I have to also be honest, I never met/seen anyone who couldn't read/write and was using an LLM, I might be very wrong here.
