on both sides of door, left and right, beyond the door casing, the
concrete of the about 2 inch high footing / stem wall , is like
"chewed" away. The sill plate on top of the footing is fine and
goes all the way to the paired 2 x 4 studs on each side of the
door opening.

But that raised concrete whatever, which is about 4 inches above the
garage slab, is for about 2 inches on the inside of the garage sort of
"chewed" away, and as you look out you can't see daylight, but as
you explore the "hole", its wider on the garage inside and narrower as
you get to the outside.
Sort of like a cone, an ice cream cone, with the "pointy" side
out.

Air is blowing in the "cones" on each side.

On one side of door, found two pieces of concrete chunks, about 1/2
inch x 1/2 inch.

Looked at the entire perimeter of the garage. Only place this exists is
right around the door frame.

I would like suggestions on what to patch it with.

Assuming reasonable access, vinyl patching cement mix would be my
choice...
