You have a fair point about the weak link for Venice of trade connections but this is also an obvious weakness to everyone. Therefore it is very obvious to provide extra protection to those trade routes, most likely to the city Venice itself. Therefore you can have so many routes to gain a lot of gold to protect those routes and the puppet states. And therefore they have the Great Galleas. It is quite obvious that Venice carefully needs to protect those routes but TR can also be a weak link for other states. With Venice's ability to puppet CS, they could make far-away outposts and raid other civ's routes.
It's pretty much highly dependable on the situation, Venice could also have CS nearby and so for land-based TR. The only thing you have to worry about is if the AI will be able to use Venice to its full potential.
