Torah Judaism is la’fukei other streams of people who believe that they represent judaism, but do not. Whether it’s admixtures of heresy from goyim in the form of tikun olam social justice, tolerance of the alphabet squad, or mixing in 19th century European Nationalism, “knowledge for its own sake” or any other sort of mixture of Torah with something else.
Torah Judaism shouldn’t have to be; it should be as you say, a redundancy, but there became a need to distinguish ourselves from the less observant or non-observant “denominations” that call themselves representative of Judaism.
