You can have LTSpice show DC voltages directly on schematic nodes. Close the plot window that automatically opens when the simulation is run. Now just left click the nodes to place the voltage markers. If the plot window is open, then you have only the probe tool for displaying plots of nodes, that's why you need to close the plot window first. The DC voltages shown are based on the solution to the the initial DC operating point, so make sure not to select "Start DC supply voltages at 0V" in the sim options.
