I thought about it again and still think I was correct (as you are) that toe trends to toe-out on the non-driven axle while the vehicle is in motion.
On the driven wheels...I guess it depends on what is "loose" and the setup in question. For a FWD car if your tie rod ends or rack bearings are loose or shot I think the drive traction would tend to toe inward. If your steering linkage is in tip-top shape but your lower a-arm inner bushings were shot you may toe outward under acceleration (forward and inward motion of knuckles/ball joints/kingpin axis with rigid steering would toe outward).
Of course this all assumes that you're running a typical tire/wheel offset that places the tread center outboard of the kingpin axis' intersection of the ground. Running extremely high backspacing wheels could reverse the tendencies for the driven axle.
For RWD live axle toe is irrelevant. For IRS/RWD it would be almost completely dependent on the exact linkage and how toe is set if it is even adjustable. For non-adjustable toe RWD/IRS (does such a thing exist?) I still think toe-in would dominate under drive torque as the tires push the suspension forward to provide the motive force on the sprung mass of the body.
