Anyone familiar with kayak rentals in Venice with a guide/thank you
Never done it myself, but I've seen them in Venice.
Tripadvisor has some companies listed:

There is also Row Venice, which offers groups rowing lessons on the back canals. Price was 90 Euros for 90 minutes pre-covid. Enjoy your trip!
We have done a kayak tour twice in Venice. I believe that venicekayak.com is no longer operating though. The BEST excursion in Venice.
I wrote about it here:

We actually just did this at the end of May! We used https://www.realvenetiankayak.com for our tour. We were a family of 5 and we enjoyed it as newbie kayakers and first time visitors to Venice. It was a nice way to see Venice differently.
