Even if we responsible party to be LLC name and its EIN, there is another question 9a Type of Entity, which asks for SSN if this LLC is Sole proprietor. 

ie, LLC, partnership, me as sole proprietor and him as employee?  

You would be operating as a sole proprietor though. 

Follow-up questions.From what I've seen, when an LLC is established, you can elect to have it considered a sole proprietor, S-Corp, or C-Corp. 

You can try to use a waiver form for the worker if the worker is a sole proprietor, but there are no guarantees that when injured the worker will not file a claim / lawsuit against you.

However, when electing to be taxed as a sole proprietor (IRS default for single member LLC) or S-Corp, I feel I've been left to figure it out myself.  

But.... if your LLC is a "disregarded entity" LLC - meaning you are the only member and it doesn't file it's own tax return choosing instead to be taxed as a sole proprietor then the activities of the property owned by that LLC are reported on your personal return. 

@Wayne Brooks does it matter if I'm still operating as a sole proprietor?

., Partnership LLC, single owner LLC or  sole proprietor.
