My point is, that it might not be possible for Kiva to have one "universal" statement on the precise, legal relationship between the "lender" (us) and the eventual borrower, since there are intermediaries (Kiva and MFI) and variations in local laws and the actual loan agreements.
It is sufficient for this discussion that a lender-borrower relationship exists between the MFI Field Partner and its borrower, no matter what the actual details might be.
So that leaves defining (a) what is the relationship between Kiva and the MFI Field Partners and (b) what is the relationship between Kiva and the individuals who fund a loan opportunity on its website.
The legal link is of a sufficient obligation to shift the risk of a legitimate loan relationship from the MFI Field Partner through Kiva to the individual funding the loan opportunity. Whatever that obligation might actually be, it needs to be clearly identified by Kiva and not denied as the current Terms of Use stipulate.
