Is it possible to assign the induction separate to the leads or do I have
to integrate inductors to every single lead?
For the most part you need to add little inductors in series with each
component. There is no parameter or something similar that adds an
inductance everywhere.
Capacitors in LTspice do have an "equivalent series inductance".
(Right-click on the capacitor.) The inductance remains hidden on the
schematic.
For resistors, if you don't mind messing up the schematic a bit, you can
use an inductor to represent a resistor with series inductance, by entering
the resistance value as the "series resistance". Unfortunately the
resistance doesn't show up on the schematic. (Annotate your schematic
well.)
People can go overboard by adding stray inductance and stray capacitance
everywhere possible. You might not want to do that. You probably only
need to add it in a few places. Also, components have two leads, but the
two lead inductors are in series with one another so you only need one
inductor per component, not two.
If all you are trying to do is simulate this circuit to see how it
simulates (and not trying to replicate an actual circuit on the bench),
then one might argue that you do not need to bother at all, with all the
stray inductors. For the most part, the circuit SHOULD work without them.
The biggest exception being that silvered wire. Inductances on the
transistor leads might also be important for proper operation (I'm only
guessing here).
