One correction: Modems in phones are not normally LGA modules, but rather components soldered directly to the main board. Sometimes the baseband processor and protocol stack are even integrated in the main processor SoC. Systems that use the LGA or m.2 modules often don't use the audio at all, so nobody has cared to make a nice interface.
