If my party casts bless on a druid and they use entangle, do they get to increase their DC that the enemy needs to beat by one D4? Also bless counts for spell attack rolls for cantrips and other spells right?
No, that's not how Entangle & Bless work. Bless allows the druid to add a d4 to their attack rolls and saving throws. When a creature is affected by the druid casting Entangle on them, the creature makes a saving throw, not the druid.
You don't know what fear is until you've witnessed a drunk bird divebombing you while carrying a screaming Kobold throwing fire anywhere and everywhere.

Bless does count for making spell attack rolls.

Bane kind of does that. It doesn't change the DC of the saving throw, but it makes it harder for the target to achieve that DC on their roll.
