Narrative:
On departure from lax runway 24L on the loop 4; we were assigned 'climb to 15000 ft.' a short time later; we were told to turn left direct to lax and resume the loop 4 (including altitude restrs). We got an RA at 10000 ft to lower rate of climb. We also heard tower advise air carrier Y to 'stop climb.' we passed about 400 ft above and less than 1/2 mi behind a heavy air carrier Y B767-400; who was straight out of runway 25. This was a potentially disastrous ATC clearance. Due to the nose up position of our climb and window frame obstruction; we did not see air carrier Y until the TCASII warning.
