Dave, best to read abb payment terms of service - section 9.2
https://www.airbnb.com/terms/payments_terms#sec201910_9
In brief, if airbnb cannot collect the money, they do not underwrite the payment to you and won't pay you.
Reading section 10 - If Airbnb Payments is unable to collect any amounts you owe under these Payments Terms, Airbnb Payments may engage in collection efforts to recover such amounts from you.
Section 10 gives timescales for payment collection as well - anyway the key phrase is 'may engage' so it would likely be a cost and risk assessment to see if it worthwhile to pursue. If your booking is not high value, it's unlikely to proceed further.
If you are taking on LT guests who book over 30 days in total, you should keep in mind how airbnb handle the payments.
There is no deposit collected from guests, so no wiggle room if a guest can't/won't pay subsequent recurring payments. If a guest doesn't pay, the 30 day paid notice is unenforceable.
