"We all are agreeing that she should have been issued a W-2 or maybe at least 1099 MISC,"

"Ultimately, we think that she should have been issued a W-2 or 1099MISC at least not 1099NEC box 1."

Nope. The Box 7 of the 1099-Misc is now the (resurrected) 1099-NEC. You keep telling us services were provided. That means -NEC or W-2 payroll, depending on the State, the program, and the employers' understanding of their requirements.

They are treating her as an Independent Contractor. Example: she is a Vet in residence at a school program, and she worked at the Zoo, independently from Zoo control.

"but for services and to cover housing, travel and food."

Because she provided Services, and for her to spend however she wanted and needed.
