I think the operative phrase is: “planning to minor in Italian”.
I planned to major and minor in several humanities and science majors and ended up in a completely different area and, I really don’t think it will help your daughter to stand out from a deluge of applicants while students who currently possess skills in American Sign language (ASL) or Tagalog may have more of an advantage.
A musician, like a Tuba player or an Oboist may be needed for a band or orchestra but that would be in conjunction with the rest of their application. Does it mean that they will go to that particular college?
