What app for LTSpice exist?I think we are saying that such a tool does not exist. It would help if we knew what kind of netlist you are starting with. For example if the netlist is from LTSpice you are done! The netlist is the schematic and vice versa. There is a small proability the netlist you have has the same relation to the graphical representation as it does in LTSpice.
Besides, how bad could it be to renter the schematic.
