This being the forum for factual questions, let’s confine ourselves to providing factual answers about lawsuits. This is not the place for rants or debates about the nature of American civil litigation. This is not the place to pass moral judgment on the OP’s scenario. We have other forums for that.

Unfortunately, sometimes lawsuits are the only way to get big business to pay attention to you. I have a feeling if I wrote to the TV network and told them they are making people physically ill with their Fear Factor commercials, I would probably get a nice form letter back thanking me for watching their network. I have found that closing my correspondence to bureaucratic robots with the fact “I am seeking legal counsel on this matter” to be an effective means of transforming their snide sneers into concerned courtesy.
Potentially you could complain to the FCC. If they’re anything like their Canadian counterparts, they can probably censure broadcasters when they overstep the bounds of good taste. That’s how we got rid of Howard Stern after you foisted him on us. 
Cable is of course quite different than radio, but I imagine it’s worth a shot. BTW, if you’re successful, please petition on my behalf to prevent anyone affiliated with Mazda from ever uttering the word “zoom” again.
The FCC only steps in if it is obscene speech. That would be a hard sell in this case. Especially since there are not special rules for commercials, and the actual show is surely grosser, and it has never been penalized in any way.
