Does anyone know what frequency LAPD uses to broadcast/simulcast pursuits on?

They don't it's always the frequency of the DIV
In addition to the Divisional Frequency it is in, it will go out Bureau Wide or on channel to adjacent division and Sometimes you will hear bits on Air/K9....
If the pursuit goes out of the division or goes on for an extended period of time, a supervisor or air unit may request for all units involved in the pursuit to be switched over to a tactical channel (each bureau is assigned some extra tactical channels to use for this situation and there a some city-wide tactical channels, as well. A few police divisions (stations) make up a geographical operations (patrol) bureau, of which there are four: Central, South, West, and Valley). When the pursuit ends, a supervisor or air unit may request for all units involved to go to simplex (radio-to-radio or local communication only) as to not tie up the normal broadcast channel. In all cases, it is the officer (radio user) who has to make the switching of channels on his or her radio; however, dispatch has the ability to "patch" in other channels.
I've been monitoring via a YouTube channel and heard one pursuit switch to a Citywide Tac, either 2 or 3. It didn't last long as it ended in a TC (traffic collision). It was either division 7, 8 or 20. With all the traffic in divisions 7 or 20 how does someone get away?
If there's a news helicopter following it, you also sometimes get interesting coverage on the 450.xxxx broadcast remote channels.
Sometimes is the key word. KABC uses a Nextedge system, KNBC is on VHF.
Aircraft VHF, 123.052, can be fairly useful if you're within range.
