I'm not sure why you're being downvoted - it's an interesting question. My understanding is that this is would not be illegal because of how discrimination laws work in the US. We have protected classes that can't be descriminated against, but we don't have a generic "no discrimination" employment law. For example, it's illegal to discriminate against old people, colored people, gay people, disabled people, etc when hiring. It would not necessarily be illegal to discriminate against neurotypical people because they are not a protected class.
