No.
I think it is much better just to go through security at the TBIT-T4 connector, much less crowded, IME.
I find security at T4 proper aggravating most of the time.

if LAX-JFK is on AA and you are eligible for Pre-check you will certainly get Pre-check stamp on your boarding pass LAX-JFK. It does not matter what your first leg was.
If LAX-JFK is on Qantas, no, no precheck for anybody, Qantas is not part of the Precheck program.
