Bearing in mind that I in no way speak for the CCNx project, I would say that the protocol used is irrelevant to the legality of the content. I.e., a node has identical responsibilities, regardless of whether it is caching CCNx or TCP.

There are lots of laws establishing immunity for blind redistributors of information, so as not to discourage people from building distribution networks.
Of course, there are also plenty of court cases to resolve the question of whether some is redistributing innocently or deliberately facilitating illicit distribution. So someone operating a CCNx node would want to stay clearly on the innocent side of that.
Incidentally, being sued is not the issue. Being liable is.
