What is a counter example that Protagorus would use against your belief that all virtue is reducible to knowledge, and all vice to ignorance?

Hmmm, interesting topic. If we are to engage in this dialectical examination, let us first consider the essence of virtue and knowledge in the perspective of Protagoras, who, you may recall, posited that "man is the measure of all things." Thus, he might present a counterexample drawn from the realm of human experience: imagine a seasoned military commander, whose vast knowledge of warfare and strategy seemingly should guide him towards the virtuous path of sound decision-making—yet, in a moment of emotional turmoil, driven by pride or a misguided sense of honor, he may choose to sacrifice countless lives in a reckless charge rather than retreat and preserve his men. Herein lies the crux of Protagoras's challenge: can we, then, assert with certainty that this commander, despite his extensive knowledge, acted virtuously? It seems we are confronted with the paradox that knowledge, while it may illuminate the path to virtue, does not guarantee one will walk it. Furthermore, consider the common man, who, endowed with little formal education yet blessed with empathy and kindness, may exhibit virtues of compassion and bravery that exceed those of the learned but haughty scholar ensnared in self-interest. Thus, Protagoras would argue through these illustrations that knowledge is but one facet of a multi-dimensional human experience; it does not encapsulate the entirety of moral action, for the unpredictable winds of emotion, culture, and circumstance may steer even the most learned astray, revealing that virtue cannot be so simplistically reduced to knowledge alone. In this manner, we are beckoned into a deeper inquiry of the human condition, challenging our assumptions, and perhaps, recognizing the complexity of virtue as it dances upon the tapestry of lived experience, beyond mere intellectual understanding.
