Presumably the project itself would be housed in an LLC, so individual developers would be shielded that way.
If the developers didn’t go through an LLC at all at any step, then yeah, they’d be liable. But if we’re in a world consistently using this sort of liability law, then presumably developers would know to use LLCs, in the same way that developers today know to attach a standard open-source license. (And today’s open-source developers can, IIUC, be liable for problems if they don’t attach the right license to their software.)
