TSB do not nullify ninjutsu by default. TSB has yin and yang by default, but before Obito got a hold of himself as the Ten-Tails' jinchuriki, he attacked Hiruzen with TSB, and he was able to regenerate, so no, the nullification effect isn't something innate to them. He was only able to control the YYR in them into the nullification effect after getting control of the Ten-Tails.
