There is component IC under eSim_Miscellaneous . You can put this component at any node and initialize it with some noise voltage. I do not have any specific example with initial condition but we do have Oscillator example. You can check it here. https://github.com/FOSSEE/eSim-Examples
opamp is used as sub circuit in eSim. You can edit the sub circuit with your design value. For more information on how to use sub circuit please go through the User Manual. You can download User manual from http://esim.fossee.in/downloads
If you want sample circuit of opamp ,please have a look at Inverting amplifier example using opamp.
LTspice is way better.I hope in the future eSim will catch up but as of now i am done with it.If you want to do a practical design its better to simulate in LTspice,its waye better and easier and use kiCAD for PCB design..
