Not the bottem of every wall do you need a kickout.
A very short wall that "has its own roof"
doesnt need a Kickout.
There is nothing wrong with this flashing job!!
It is the non matching sealant at the top of your eye level side roof that is offending you.
He shouldnt have used that black sealant there.
It just doesnt match and it is staring you in the face right there at eye level.
He should have used the brown.
peel, cut or go over the black sealant
with a brown polyurethane sealant.
Just prepare roofer to have brown polyureathane caulking BEFORE he gets there, ok.
He will satisfy you.
Just know that a roofers bead of exposed sealant
Is a whole lot bigger and isnt as attractive as a painters bead of caulk that is made to be invisible.
Be nice please.
God loves you!
