LLC will only help you to shield future personal liability

if you can be compliant with all the corporate formalities and not to co-mingle your personal assets with the LLC income. You need to consult a good attorney, not an accountant, with respect to establishing such an entity. As for the trust, I believe a recovable trust will NOT help you in that regard. However an irrevocable trust is very inflexible and has some income tax disadvantage. Plus, your heirs may also suffer some capital gain tax consequences if you keep the property in an LLC and/or an irrevocable trust.
