Not sure the US Department of Education did much that would influence this either way, except if the AI was being used to correct income-disparity effects on education.

It doesn't mandate curriculums, choose technology, anything like that? Only recommendations.

They might have been able to monitor its effects but they wouldn't have been able to direct its use or non-use; that's not what they did.

Essentially it was/is an anti-discrimination organisation, making sure that states gave an education regardless of wealth/race/status.
