Does War God's Blessing affect Bigby's Hand's attacks?
The description states that a creature can benefit from it, but the hand is an object. PHB pg.63:
When a creature within 30 feet of you makes an attack roll, you can
use your reaction to grant that creature a +10 bonus to the roll,
using your Channel Divinity.
On the other hand, the description for Bigby's Hand attack states that the attack roll is made using the caster's stats, not the hand's, so one could argue it's an attack made by the wizard, therefore justifying the Blessing. PHB 218:
The hand strikes one creature or object within 5 feet
of it. Make a melee spell attack for the hand using your game
statistics.
What's the correct interpretation for the blessing in this situation?

It will apply to an attack roll made for a Bigby's Hand only if the caster/controller of Bigby's Hand is within the Blessing's range when they make an attack roll for something they are making the Hand do. The Hand does not have to be within range, since it is not making the roll and is not a creature anyway.
This is because it is the caster/controller who is making the attack. Bigby's Hand makes it clear that it's the caster actively doing the attacking, merely using the Hand at a remove to do so:
In each way that the Hand can attack, it is the caster actively controlling the Hand and contesting the caster's own ability (their attack bonuses and rolls) against the enemy the Hand is attacking.
