This is true of most companies that provide transactional funding, although there may be a few out there that don't have this requirement. Keep looking... Google "transactional funding" and check out every website to see if the property has to be purchased in the name of a company. You don't really need to talk to anyone initially... the POF form will say whether a company name is 'required' or not. There are also some members on BP that provide transactional funding, so you can check with them. Worse-case scenario is that you will have to go ahead and get the LLC.
Borrowing the money from someone is certainly an option. And you're right, it is a big risk for you but also for them because there is nothing whatsoever to secure the loan with.
John gives a good suggestion for the EMD if you don't have it yourself and can't borrow it:
Your end buyer can supply the earnest money deposit (since you should be getting a non-refundable deposit from them anyways). So hopefully you have been building your buyer's list and have someone in mind for this property.
You will definitely need to figure this out if you don't have an end buyer yet because, once your offer is accepted, the bank will typically only give you a few days to present the EMD along with the signed contract and addendums.
