It seems you refer to a wrong PMP reference design. Can you double check? LEM sensor seems to be current sensor, which LEM sensor are you referring to?
Sae,
I haven't use LEM sensor before and also not familiar with LV 25-P. But for AC voltage sensing, you can use resistor dividers. One from Line to primary ground: V_Line_sense and the other one from Neutral to primary ground: V_Netural_sense.
C2000 ADC can take both signals and do a differential operation: V_Line_sense - V_Netural_sense, which will give you AC voltage sensing result: V_AC_sense.
You can refer to TIDM-02008 for AC sensing method we are using.
