Well my learned aero profs at Parks College always taught TOE IN.

When a conventional gear plane is up on the mains and rolling, if the plane yaws SLIGHTLY, say to the left, then the left wheel now rolling parallel to the line of motion and has a lower rolling resistance. The right wheel is now scrubbing, creating a higher rolling resistance, creating a force that pushes aft on the right wheel, thus stopping the unwanted left yaw an re ballancing the drag between the two wheels.

Toe out does just the opposite. It makes the initial yaw worse.
