Anyone, can and will sue anyone, for anything, IF and ONLY IF, the attorney believes they have a reasonable chance of getting paid. Either through a settlement via insurance, or assets from the other party.
There is a well documented case in phoenix years ago where a child was electrocuted by a base ball field light pole. The attorney for the plaintiffs sued everyone who had ever worked on that pole, (the company that originally installed it, and the companies who had provided service since) the makers of all the components (wire, lamps, connectors, ballast, steel, certifying agency, etc)
The thing you have to ask yourself is what type of personal assets are you willing to risk, and who is standing in between you (that more than likely has WAY more money) and the guy first in line.
If you have sizable personal assets, I strongly suggest you have a 1MM or greater umbrella policy over your homeowners. If your in debt for most everything you own, I would not give this a second thought. that club with its insurance policy is standing between you and that plaintiff.
