Someone Is Falsely Alleging My Dog Bit Them And Trying To Sue My Home Owners Insurance.

I got a certified letter from a lawyer about 2 months ago claiming damages to a person caused by my dog. Today, I received a certified letter from a different attorney from the same person claiming a dog bite. They are requesting my homeowners information and any home security footage I may have. The thing is, I have no idea what they're talking about.

I am in Georgia. I have an American Bully that is confined to my yard with an electric fence. I have not had any visits from animal control or law enforcement over this. I have contacted my homeowners insurance, and they have assured me not to worry. I have not given this person's lawyer my homeowners information as of yet. Can they really claim my dog bit them and sue my homeowners insurance without anything on record?
