Set the Fillet Radius to 0

 

Newer AutoCAD can use Multiple option. https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/FILLET-and-CHAMFER-multiple-sets-of-lines.html

 

Maybe something here works for you.

Works only with lines. Polylines are not supported.
If the AutoCAD version is localized, then
(command "_fillet" obj1 obj2) and (setq ss (ssget "_F" fpts (list (cons 0 "LINE"))))

i also tried it, it is working. You just need to adjust it a little to your needs.

If your autocad language is not english, you need to add an underscore for the ssget "F" so "_F" and for the filet command.
Also you would need to change the ssget filter to use lwpolylines instead of lines and add a pedit command to actually join them after the fillet.

Edit: ok its not working with lwpolyline tough i dont get why

This has been a long time problem in calling the FILLET command within AutoLISP (Google it - there is allot of forum posts out there).

When typing in the FILLET at the command line in AutoCAD, it works with Polylines, but it doesn't work when called inside a (command) statement. As far as I can tell, noone has provided a solution, other than using direct object manipulation (via ENTMOD or with VLA; joining and setting bulges).

 

EDIT: NOTE - it will work for me if the Polylines are 2 separate objects, but if they are already connected into a single object at the corner, it won't work.

I will have another look at it using *LINE will detect plines but did find another problem on a certain pattern of linework. Updated.

Will improve a bit more.
