Hi and welcome to JA. Ray here to help you today.
No you don't have to do anything.You aren't liable for the debts personally.You advised the creditor that there was no probate and the deceased died insolvent thats all you are required to do here.Not sure why they will not close this out.If you get more letters throw them out or put deceased/return to sender on the mail and put it back on your box.Eventually they will get the idea that there is nothing here to pursue.
I appreciate the chance to help you today.Sorry they are hassling you here.Time will take care of this.
