I really don't see how you can blame the larger dog since you were "watching" the larger dog. Either way I think it goes back to you. I cannot see how the larger dog's owner would be responsible for something that happened while the dog was in your care.
No if this question is directed between you and your mom... split it.

Do most large dogs act violently against little yappers?

My brother has a pitbull and my sister has her own large chocolate lab who get along fine with the little barnacle.
