This is common and a part of learning to fly.
Do not "off set" the wheels. This will only creat other problems.
What you need to do is use the rudder. Start out with a slow roll down the center line of the landing strip. A slow start will have less of a pull to the left, fast starts can pull you quickly left. Watch to see what the plane needs, feed in some right rudder as the plane needs it. Your goal is a smooth straight roll down the runway.

Keep the rudder input in even after lift off, if the plane needs it. The goal here is to keep the wings level and the airplane flying straight.

Just takes a little practice. Remember slow starts are easier.
