She has asked me to call her by a new androgynous name, similar to her nickname, and to use they/them. It's not entirely clear to me what she has 'come out' as, possibly agender.
I agreed to try and use her preferred name, but said that I could not use the neuter pronouns, which she accepted.
She's just a teen who is slower than average to develop feelings of sexuality. She's probably on the autistic spectrum. She's a normal, emotional-rollercoaster, half-grown-up-half-child, confused teenager. But everyone has to have a label. The only way you can belong is if you have An Identity. You cannot just be.
She's classic trans-ideology fodder.
One more thing to worry about.
