Yes, you will need an EIN from the IRS. You will not be able to obtain an EIN online from the IRS website because it requires a social security number. As a US nonresident, you will not have a SSN. You should consult a Florida attorney to discuss tax issues to determine if the LLC is the most appropriate entity.
I agree with Counsel. For purposes of tax reporting a single member LLC is a disregarded entity and the member pays taxes on their personal reporting. Being that you do not have a SSN, that will become an issue. Please consult a Business Tax Attorney locally to discuss the LLC tax implications. Good luck to you.
