I'm not really sure sv_alltalk makes dead players talk to alive ones, at least it doesnt in CS:S and I have no way to test it in TF2.

But if it does, then replacing the big if-statement at around line 140 with this one should fix it:

  if(!relay_mode
  || !client
  || !p_bctype[client]
  || dontBroadcast
  || IsPlayerAlive(client)
  || GetConVarInt(FindConVar("sv_alltalk")))
    return;
