As long as the first two letters in LLC hold up, lots of people would be willing to enter into a new market that appears to have a lot of potential upside and profit, with the downside limited to whatever they invested, or borrowed, to get it going.

And in that case, any indemnity clause won't be worth much - the manufacturer will end up paying most of any claim

There are a lot of fools out there. The real question is whether a clickwrap indemnification would hold up in coult; I suspect it wouldn't.

Why wouldn't it? People are agreeing to indemnify and hold manufacturers harmless all the time. IANAL though.
