The ticking actually should be there whether the effect is "on" or "off".
LFO ticking occurs because the standard 2-op-amp LFO produces a square wave and then smoothes that out into a triangle for modulation purposes. The initial square wave produces a sudden current draw, which is heard as a spike on the power line shared with any other parts of the circuit, including the audio path.
If it was the case that the CE-2 was true bypassed, then when "off" the straight wire would be unaffected by any nonsense going on with the power line. HOWEVER, the CE-2, like indeed the vast majority of chorus pedals, keeps most of the audio path in circuit, during both bypass and effect modes, and simply uses a single FET to disable the wet signal for "bypass". Any spikes on the supply line are experienced by the dry path as well.
De-ticking such pedals benefits from a multi-pronged approach. One prong is certainly to use a low-current op-amp, like a TL062, TL022, or LM358 - commonly used in such applications - such that the current-draw is reduced. A second prong is to decouple the supply line for the LFO-dedicated chip from the overall supply line. So, normally, the V+ pin (pin 8) of the chip would be tied directly to the 9V supply. To decouple it, one would insert a small-value fixed resistor between pin 8 and V+, like 10-100R, in tandem with a medium-small electrolytic cap value (10-33uf) from pin 8 to ground. Think of the RC combo as being a bit like a micro-battery or pocket money. If what you want to buy is cheap enough, then pocket money is sufficient and you don't have to go to the bank or ATM. If the expense is big enough, though, you DO have to resort to a deeper current-well, like the bank. IOf teh current stored in the cap is enough for the chip to produce that initial square wave, then there is no draw on the overall supply, and no spike/tick produced.
