I don't know where you got the impression that the F-15E can't take care of itself air-to-air.
An F-15E in capable hands is the third most lethal platform in A-A combat right behind the F-22 and F-15C. All the bad guys in the world know they will get their clocks cleaned in an engagement with a cleaned up F-15E.

your words even speak to that ...You say it can “take care of itself”....correct ...it can defend itself ... that’s its mission get in attack ground targets and get out without being shot down... in air to air ...it’s always a defensive mission for it...it’s not an aggressor in aerial combat
F35 need to be able to defend itself against fighter out to shoot them down.... The F35 not going to be defending itself against other ground attack aircraft that can defend itself ..like an F15e
The difference is between an aircraft assigned to be on the offense against other aircraft in the air versus aircraft on defense in the air...
The F15e is carrying a lot of things that are virtually no use in the offensive air-to-air combat mission... it’s not an air superiority aircraft... it’s a ground attack aircraft that can defend itself and you don’t use it to attack other ground-attack aircraft.. and you sure as hell wouldn’t use an F15e to attack air superiority fighters...
