How to draw an impedance in LTSpice?
What you are looking for in are called devices, and you combine devices (some non-linear, some linear) to get the result you need:

B = GaAsFet
C = Capacitor
D = Diode
E = Voltage Controlled Voltage source
F = Current controlled Current source
G = Voltage Controlled Current Source
H = Current controlled Voltage Source
I = Indépendant Current source
J = JFET
K = Mutual coupling
L = Inductor
M = Mosfet
N = Digital Input
O = Digital Output
Q = Bipolar Transistor
R = Resistor
S = Voltage controlled switch
T = Transmission Line
U = Digital device
V = Indépendant Voltage Source
W = Current controlled Switch
X = subcircuit call


alternatively you can use the .MODEL statement and AKO reference (AKO = A Kind Of syntax)
