To your first question:

Hydra can be a great item if you want to bolster your damage a bit and have more AoE damage during a teamfight. I played a bit with it on Sion relaunch and thought it worked pretty well.

However, it does nothing to increase your tankiness, although it does provide you with a good bit of sustain and better damage output, as well as stronger waveclear.

To your second question:

Yes, the passive splash damage of Tiamat/Hydra (splash damage) can and will be applied by Sion's basic attacks during his reanimated state.

The same holds true for other persistent on-hit effects, such as Frozen Mallet, allowing for Sion to become even more of a nuisance as enemies try to escape him after killing him.
