I've never seen an LC oscillator for audio frequencies unless two for mixing like in a theremin. Normally audio uses RC circuits. Tremolo is AM and vibrato is FM, right?

First you trolled your circuit and now you're trolling yourself by ignoring the fact that you have two independent and _grounded_ inductors that are _not_ a single L but part of a network.

A PI network (4-pole, not 2-pole) can be either CLC ('Colpitts') or LCL ('Hartley'). Now you trolled away the important capacitor, C3 in your earlier circuits, so as not to see the network.

For equal L's (your case) the required loop gain only needs to cover the (small) losses. Yours is insanely large and the result resembles a blocking oscillator.

Yes, it oscillates. What does that tell you? I'm in the timezone, good night.
