Another hard money LLC question

[Bienes Raices]

This is sort of similar to a post I made a few months ago (sorry), but there is a difference...

If you invest in fractionalized notes (is that the correct term?) through a firm, rather than becoming a solo hard money investor, should you still make your investment using an LLC? Or does the firm that's handling the mortgage and all the business take all the legal risk, and I just act as a back end investor, just as if I were buying a stocks or mutual funds? Thanks once again.
