Being an LLC is certainly not a magic shield that protects you from all care and woe, and you might find that it is relatively worthless in particular situations. If you have employees, an entity can protect you personally, as the owner, from some liabilities of the business arising out of the employees acts or omissions, but probably won't protect you from the impact of your own acts or omissions. There are a great many more situations to think about, including what insurance covereages you ought or will be required, to have.
