So does Torbran work with cards like Acidic soil meaning it will do 3 damage per land a player controls or with Thermo-alchemist which would do 3 damage to each player when it is tapped.
It works with those cards but not exactly the way you think. For the Alchemist, it will be 3 damage to each opponent since Torbran will modify the damage to each player.
However, with Acidic Soil, it is not 3 damage per land. It is 1 damage per land + 2. So, if the player has 6 lands, they are dealt 8 damage.
Also, this should be in the Rulings forum. You will get a quicker response usually if you post Rulings questions there.
