You have several choices. 1. Add voltage or current balun at tuner output. Voltage 4:1 is simpler.
2. Connect the ladder line directly but loop the coax by the tuner a few times around a large toroid. This is equivalent to adding a balun. Do not ground the tuner. The first option guarantees balance but may add some losses. The second one is trivial to do. Most likely you will not be able to tell a difference. I used to have 70ft dipole at 25 ft fed with ladderline all the way to the shack. Matched by MFJ-962C, which had internal balun. Never a problem with up to 500W and even worked coast to coast on 160m!
