Caesar didn't "introduce the voi". Is this an urban myth that Italians believe? The tu/vous distinction in Romance languages arose in medieval times. Not only did it not exist in Caesar's time, it is absent from the centuries of Imperial-era literature in Latin.

There is a wide literature on Latin forms of address. Eleanor Dickey's monograph published by Oxford University Press is a good survey.

I am not an historian but it seems so, I’ve found in the past few minutes two sources that attribute Voi to romans, its in italian but sure it can be translated, going to paste the original links unaltered

Beware the treccani is the most used/influential encyclopaedia in italy, so I’d tend to say that i trust them a lot

Your first link backs up exactly what I mentioned above:

> In antichità, quando si parlava latino, le formule di cortesia non esistevano … L’usanza del Voi nasce insieme a una nuova formula politica: la tetrarchia introdotta nel 293 da Diocleziano.

It was an innovation in Romance that took place centuries after Caesar and most of the Imperial era. Again, there is ample scholarly literature on this, so no need to resort to popular references like encyclopedias.
