Do doctors have to remove blood because of to much volume in the human body?

That idea was held until a few hundred years ago. When a patient was sick with
certain kinds of ailments, doctors would "bleed" the patient, presumably to drain
some of whatever was in him that was making him sick.
Near the end of George Washington's life, he was weak and sinking, and doctors
'bled' him. When it didn't seem to help much, they bled him again, and I believe
they eventually bled him a third and maybe even a fourth time, until the effect
was clear ... he died.
There are procedures in modern medicine where some blood is removed.
Nowadays, it can be blood taken out of a healthy person, and used to replace
blood lost by someone else, either during surgery, or as the result of a violent
injury. Or a person may 'bank' his own blood for use during his own surgery.
But it's never taken out on account of 'too much blood', or to let something
out of a patient that's making him sick.

Why does an increase in blood volume result in a decrease in blood pressure?
It doesn't. The opposite is true. Blood pressure is proportional to blood volume. The greater the blood volume is, the higher the blood pressure will be. This is because there will be a greater volume of blood flowing through the blood vessels which means that a greater pressure will be exerted on the walls of the blood vessels, which means increased blood pressure.
