A TRIAC is a switching device which will generate harmonics in the
power drawn from the mains. Some of the power may be reactive power
but most is real power that light your bulb. The voltage and current
are both in phase even if waveform is a distorted.
No, the main voltage is not distorted. if you measute before the triac
there is a phase offset for every phase angle not 0 or 2*pi (more or
less).
I am just not seeing the reactive component; the TRIAC does not cause
a phase shift in the relationship between voltage and current. I think
only the load can do that.
