Op amp Power supply splitter with totem pole
But while I was looking at it, I noticed that since both transistors need to be (almost/close to) half way open, they will act like a resistor and will just sink current to GND (the original GND) even if I do not use the new &quot;Virtual GND)

In your circuit (an op-amp follower buffered by a complementary emitter follower), always one of the two transistors will be off and the other will operate in active mode (as a single emitter follower) as follows:
If the return current tries to enter the buffer (the device &quot;blows&quot; current through the load into the buffer output), the virtual ground will try to increase. The op-amp will sense this increase and will decrease its output voltage with approximately 0.7 V so the virtual ground will stay exactly in the middle. The return current will pass through Q2.
If the return current tries to exit the buffer (the device &quot;sucks&quot; current through the load from the buffer output), the virtual ground will try to decrease. The op-amp will sense this decrease and will increase its output voltage with approximately 0.7 V so again the virtual ground will stay exactly in the middle.  The return current will pass through Q1.
As you noted, it is preferable that always &quot;the two transistors act like a resistor&quot; connected between the supply rails or, more precisely speaking,  like a voltage divider. For this purpose, you have to insert a biasing network between the op-amp output and bases consisting of diodes and resistors like in the similar circuit diagrams below:

Fig. 2. Push-pull stage at zero input voltage (OP's case)


Fig. 3. Push-pull stage at positive input voltage


Also, which is my return path for current for the devices I power from the new &quot;Virtual GND&quot;? Is it the Virtual GND or the original GND?

I think the answer is already clear - the virtual ground.
It would be extremely useful for you to draw the full paths (loops) of the currents in all cases like in the pictures above.
