Ok, have you had anyone explain to you what a TORCH infection is?
She caught something before she was born or while she was born that has damaged her brain.
Here is what I found:
"TORCH infections are a group of congenitally acquired infections that cause significant morbidity and mortality in neonates. These infections are acquired by the mother and passed either transplacentally or during the birth process. While each infection is distinct, there are many similarities in how these infections present. It is important to consider TORCH infections whenever a neonate presents with intrauterine growth restriction (IUGR), microcephaly, intracranial calcifications, conjunctivitis, hearing loss, rash, hepatosplenomegaly, or thrombocytopenia.
Although the five classic infections are discussed here, the “other” category now also includes HIV, VZV, parvovirus B19, enteroviruses, and others.".
She's going to be a special needs child/person her whole life.
This is a really complicated condition that your child has and there's no way strangers on a web site can give you any meaningful medical advice.
Please keep working with your doctors and it might be helpful if you can find a support group.
