They are using a private organization structure to try to loophole the civil rights act. Of course, it's a violation none the less, just with extra steps.

IANAL, so I don't really know how you'd build a case against them, let alone one that the current supreme court would actually hear (if that case would even get that far). The Supreme Court can absolutely say the quiet part out loud without saying anything, simply by refusing to hear the case. It's also entirely possible that this organization could get struck down by courts at such a low level that the ruling has no substantive effect outside their county or the state.

Fighting bigots has always required grassroots efforts in conjunction with federal support. Remember, the last time a president deployed the National Guard to a state without the governor's (of that state) approval before the recent California incident was when Lyndon Johnson sent the National Guard in to protect the civil rights of students against this kind of institutional racism at the local level. But, as you say, this administration has obviously abdicated their responsibility the rule of law and the rights of most of the population.
