I don't understand what you mean. It reproduces the racism of the authors, no? It's just an extension of the producers. Like I guess you could say the hammer in the hand of a racist hitting you isn't itself racist but I think the point of people saying some tool is racist is to say that it is in some way designed to reproduce their own racism (even if completely accidentally and unintentionally.) But is something designed so like a hammer or is it something more specific?

Compare it to industrial accidents. If a lathe hurts a black person, that's not racism on the part of the machine (obviously) or on the part of the engineers who designed the lathe (obviously). However, if the machine shop company pays less attention, though through no conscious choice, to safety in their branch on MLK street, that's systemic racism on the part of the company.
