“Indian” for the indigenous inhabitants of the Americas is not racist, and “Native American” honors an Italian, Amerigo Vespucci. Anyway it’s offensive to have a horse in the painting—that’s cultural appropriation. The Indians didn’t have any horses until the Spanish brought them over.
They didnt have little pointy roofed cabins either.
Now we know that the war band burning this farmstead were likely post Spanish influence and likely before English control.
