I jungle voli and have dabbled with support voli in the past.
Voli will be a heavy engage support that is very binary. In a voli player mind the perfect time to go in is based on 2 conditions. Are the QW abilities off cool down and is the enemy at 50% health or lower. With W being an execute these are literally GO conditions for the player. They are counting on safe backup from you (some damage for the execute) but they are banking on the passive more than their lane partner.
This is a high risk lane style and if it does not snow ball becomes almost useless later in the game. The voli player is going to bank on the mistakes of the enemy instead of the skill of him self. Which is why you are seeing this in bronze level of play.
Voli support is not really a thing. Play conservatively till the support engages and do your best to follow him up. Try to do do one sided poke so the voli player does not run into 2 full health targets. Out put as much damage as you can safely , when the voli charges in. Expect that the voli is going to take the kill so do not over extend, your gold is going to come from lane CS and bouncing the wave into the tower.
