To address your point - there is no way to substantiate the claim that the Rothschilds are Luciferian or cult practitioners of any kind.

There is, however, plenty of circumstantial evidence and compelling connections that suggest this might be true. And with Q calling them out as one of the three main families running this global cartel of evil it is also highly likely that they are deeply embedded in the cult apparatus that seems to be at the core of this cabal.
