Hi guys, the mosfet is a simmeteycal device(Drain and Source can be exchanged on layout) , right? But when i do LVS in netgen, i need to Flip some mosfets around their gates to fix match problems even if the LVS has the same nets and devices. Could i consider the mosfet as simmetrycal in LVS?

Make sure you're using the correct setup file.

@User Yes, drain and source of a MOS-FET are permutable, and I see no issue in my layouts with LVS. You should double-check your setup, as @User mentioned.
