KiCAD: Footprints for {Axial, Horizontal, Through Hole} Resistors
The footprint for an axial through hole resistor is typically just two through holes and a courtyard/keep-out for the part body and leads.  Because you can bend the leads however you want, you have a lot of freedom in how you design the footprint.  There is no one-correct way to do it, and there may be many footprints in the library that would actually fit.
The DINxxxx numbers refer to the size of resistor.  Beyond that I can't really say specifically what the sizes will be.  If you are unsure you can always open the footprint and measure it.
Making a footprint in the Ki-CAD footprint editor is really easy.  If you can't find one you want in the libraries, then just make one.
The only restrictions are...

The hole diameter is appropriately sized for the leads.  Usually this is something like lead-diameter + 10 mills.  In your case 0.6mm + 10 mils = 0.825mm holes.
Unless you are doing something strange like bending the leads in a U shape, the distance between the holes needs to be at least a far as the part-body length + 2x the allowed lead bend radius.  The minimum bend radius is usually something like 3X the lead diameter.  Given you body diameter the hole spacing would be 6.8mm + 6 * 0.6mm = 10.4mm.
