Quitclaim it to him. There are scenarios where dissolving the LLC IF there is any potential liability out there against it (e.g. any unpaid bills, any fulfilled contracts, any debts, anyone injured on property it owned, etc.) could result in the members or former members (at the time the liabilty was incurred)  being liable, since dissolving the LLC while there are debts, obligations, etc. outstanding could possibly be seen as an attempt to defraud creditors. Quitclaiming it to him, the LLC--and it's liabilty protection--will remain in effect.
