ME, that's not true.
Whilst the main platform for an F-35B might be an LHA-R, as with with the AV8-B it needs to be available within 5m of the troops o the ground.
The usual means of doing so is to cycle forward to an onshore FOB where you can refuel re-arm near the FEBA. That's normally done on a PSP or quickly laid concrete platform.
If there's a larger length strip it will be used by forward deployed USN or USAF units with greater payload and sensors.
If you assume an LHA-R within effective range, you must presume a CVA to protect it, in which case why the LHA?
