What kind of ships will be part of a Type 076 LHD led Expedition Strike Group (ESG)? Would the Type 075 LHD be part of it as well? It would require at least 2x Type 052D right? or would it also use the Type 054B?
This depends on the strength of the enemy, location, the type of missions and what ships are available. You can imagine dozens of different combinations.
Basically, you would want a strong escort to protect your fleet, i.e. defense against air, surface, under water, electronic counter measure, enemy shore based anti-ship missiles, sea mines etc etc.
So the fleet combination could include aircraft carrier, all kinds of landing ships/craft, DDG, FFG and submarine. If the enemy is is, say a certain nation south of Taiwan, you may not required aircraft carrier and submarine, and can have smaller number of DDG and FFG.
Example of aircraft carrier with type 075 LHA training together.
