You’re right that Native American or Indigenous is the preferred term in most of the United States. With that said, I used to live in South
Dakota (which has a very high Native population) and Natives there really did prefer “American Indian.” That term was used everywhere (by indigenous people), while Native American and other terms were not.
So it really depends on where you are.
