Bismihi ta'ala
Firstly, I would recommend you watch this presentation, and although it might be bit technical for her, you would be able to hopefully explain it in a way that she understands:
Basically, in Arabic language, pronouns do not always necessarily need to refer to gender, and we most certainly know that Allah ta'ala is above gender, but we must refer to Him with something.
In the English language, he/she in most cases only refers to gender, so the problem could be due to the language as well. Whatever the case may be, we still need to address Almighty God with something, as long as we know and understand that it is not a gender based usage, because Almighty God does not have a body or a gender.
And Allah knows best
