> the Veneti (ancestors to modern Slavs) lived around Veneto

This is inaccurate. The ancestors of the Slavs spring, according to the consensus view, from around where Ukraine, Poland, and Belarus meet. So, very far from Venice, let alone central Italy. We have attestations of the language that was actually spoken around the Venetic region[0], it is not Slavic. Why the early Slavs were often labeled with an ethnonym resembling Veneti is a complex affair[1], but it does not mean that the Slavs had any meaningful contact with central Italy.
