Is "Talk no Jutsu" actually a thing?
It's a joke, a glance at the home page of the Konoha Libraries site you provided says:


  Remember, there's plenty of serious information banks on Naruto already. We will never be as big as any one of them so just have fun with your articles. Go nuts. Reference people from the forum or threads you love. Just remember to keep it in good spirits.


Talk no Jutsu refers to the ability of Naruto (and many main characters from many anime series) to talk the antagonists out of their evil ways, and "show them the light".
