Nope. Many of these compromised routers and webcams are not based on U.S. soil, so they're outside of U.S. jurisdiction. But even if some enterprising lawyer could attach a legal claim to them, most of these guys are tiny, and while you could easily sue some individual companies out of existence, it would not have much impact on the broader problem.
That's probably too distributed a set. You'd have to hit the device manufacturers (say, ARM or Intel), or vendors (Amazon). Hold them liable for problems.
Hit the distribution channel and I suspect you'll see a rapid increase in accountability and security measures.
