What are my options if my dog bit a neighbor when I pick up my son on a property where dogs are not allowed?

In December one of the dogs on the property killed a neighbor’s dog. The dogs were removed from the property. Dogs weren't allowed on the property at all. I brought my dog back to the property to pick up my son and my dog bit the neighbor on the sidewalk. I agreed to pay for the hospital bills. The dog was put down and just got served for the homeowners insurance. We don't live there or on lease. We did live there prior temporarily. What can I do from here? I would like to not have the owners involved since they weren't allowed in 1st place. Our negligence is on us and would like to be held 100% responsible.
