My breaker box is installed flush with the drywall, however I need to run some 6/3 romex out of it to a charging box for a Tesla.
My thought was to come out the bottom of the breaker box, then a few inches down, come out of the drywall and run the wiring from there to my charging box.
Is there any sort of box to make the wiring coming out of the drywall not look like…a wire coming out of the drywall?
Perhaps cable clips like these.
I would drill a hole through the base and install them with metal screws into the edge of the stud, then insert the cable. The hole into the metal edge of the stud should be pre-drilled.
If they fit, I would use several to ensure that the cable did not stray into the door channel.
There are also cable clips that use zip ties, as suggested by DA01.
The illustrated ones are too large (1"). You may be able to find smaller ones or cut these down. Mount as discussed above. After mounting the clip, thread the zip tie through the slots and around the cable.
While nailing into the finished wall in this vicinity is not very likely, you need to be careful since the power carrying cable will be very close to the back of the plasterboard. When installing the casing, be sure that no nails stray beyond the stud (they shouldn't anyway).
Technically, exposed NM wire should be protected from physical damage, especially in heavy traffic areas like kitchens.
For your situation, a 1x1 piece of wood to buffer any accidents is all that is needed.

As was mentioned in comments, you can't use Romex or other-brand NM cable stapled to the wall surface. Since conduit is required for protection you can save yourself some trouble (wrestling and conduit up-sizing) by using THHN or similar conductors instead.
An "old work box" can be installed in a finished wall. Cut a hole just the right size in the drywall and slide the box in. The old work box provides the path from in the wall to the face of the wall. Old work boxes are available in plastic, but because conduit and THHN are recommended here anyway, I'm showing a metal old work box. You can connect this up to the circuit breaker panel with a pre-threaded rigid conduit nipple or with a segment of conduit and appropriate connectors.
So, with the old work box providing the pathway to the wall face, next you need to transition into conduit on the wall surface. An easy way to do that is to stack an extension box on the front of the old work box. Conduit exits one of the side walls of the extension box and a blank face plate goes on front.
