@Charquis M.
What are you looking to accomplish by establishing the LLC? In general, this is a risk management strategy, there is also a tax strategy that could be involved (talk to your attorney and/or CPA).
As mentioned, if there is a mortgage, the bank can call the loan (highly unlikely if payments are being made). There are some costs involved with creating and maintaining an LLC. Another risk management strategy would be to purchase an umbrella policy (some property manager may require you to have one to manage the property), this, in essence, covers you for a range of extended risks.
A more prudent risk strategy would involve both. Also, consider what your equity in the property is. If you owe 90% of the value, the likelihood of someone suing you to get that 10% is not very likely but if you own the property free and clear attorneys are more likely to take on those cases since there is more money available to settle.
