I think they're basically saying that one thing they like about the show RWBY is the American jokes and behaviors in it. As I understand it, that's actually part of RWBY's allure in Japan - it stands out among animated shows made there because of the American influence in it. Miles and Kerry write it in a different manner than someone born in Japan would have. But this novel is written by someone (presumably) born in Japan, so it doesn't have the same feeling to it that the show has.

As for "mass-producing fantasy novel", I think they're saying that's their best translation of what kind of novel they were trying to talk about. They're not saying that they think the translation for "isekai" is that.
