dxf2gcode does have an option to enable Cutter Compensation.  Cutting inside the line and outside the line is controlled by which code is used and the direction of travel.  G40 cancels cutter compensation.  G41 is left compensation and G42 is right.  Lets assume you want to cut out a disc and the travel is clockwise.  G41 would be selected and the cut would be on the outside or left of the line.  This would leave you with a disk of the correct diameter.  If you wanted a hole, use G42 to cut on the inside of the line.  The opposite would be true with counterclockwise travel.
