LLCs can be pass-through entities or corporations.
EIN application is not a requirement for all company structures. See 'disregarded entities' or single member LLCs. Resident single members can use their SSN instead of an EIN though that's not normally a good idea as it erodes limited liability. In this case, and in the case of a partnership, you are definitely not an employee in the eyes of the IRS.
Any foreign corporation can be a member of an LLC. In a single member configuration the LLC would have zero US filing requirement.
