Since she doesn’t mind MVC but does mind AP gov, the solution seems to be MVC + regular Gov+fun elective. A fun elective senior year is good to have in any case 
To answer your more direct question: no, adcoms will not mind her not having AP Gov. It’s not a core Ap and there’s no expectation students will take every AP their school offers as long as their schedule is rigorous and makes sense, which hers does.
