Since the LLC is in your name this is what I would do, but I tend to take a hard line, check with an attorney, even if its just a one time consultation:
1. See if you can just completely close the bank accounts. Open new ones in your area and the LLC's name. Do not tell him where since he is not the owner on the main one and because he took disbursements in violation of the LLC agreement for the lower one. This is called embezzlement. Change the address for everything associated with the LLC -utility bills, property taxes, whatever, to your address.
2. Contact Airbnb and tell them that you own the houses and are not allowing the other person to rent them out. Please remove and block listings for those properties. Cancel all current reservations. The property is being sold.
3. Transfer the property to your name by selling or whatever your LLC allows to make you whole. Consider the $ your ex-partner took out for personal use and try to match that amount to distribute to you if you transfer it for more than the mortgage. That way you can justify keeping it all. Then change the locks and list it with a realtor that only answers to you. Goal is to sell it quickly before he can react. Alternatively, if there is no equity in the property do a friendly foreclosure between the LLC and you mortgage holder. Have them agree that they take the house back, your LLC owes nothing and they do NOT report a benefit to the IRS for which you owe taxes. This could work if there is some equity over the mortgage owed to cover their costs, but not so much you lose out. You could do this on some property but not other property.
4. If he asks about the LLC, tell him the main one is none of his business and you will not be discussing it. The sub LLC will be closed after the taxes are filed next year, and he will get the bill for his share if the LLC does not have enough $ to cover the LLC's legitimate expenses. Plus you will be filing a lawsuit for the records of income, expenses if needed, so taxes can be filed without criminal errors. And after your (not his, yours) accountant looks at the ledger you will be telling him how much he owes which he will pay you within 30 days or you will see him in small court, and file criminal charges against him for embezzlement. Make it clear that there are consequences for his embezzlement.
5. In the future, NEVER give up financial control for something that you are responsible for filing the taxes on. NEVER, if the IRS is holding you responsible, be responsible.
6. Keep the main LLC. Let it go inactive, but you set it up so now you have it if you need it in the future.
7. Know that this too will pass and be thankful he is known for what he is and shortly will be out of your life.
