If I have understood the previous posts correctly, a tilt EQ is even
simpler than two shelves: just use a single one at the desired tilt
frequency and adjust the overall gain, like Fons mentioned: if you dial
3dB treble boost, applying -1.5dB of total gain should give you the
exact equivalent of a tilt EQ. But I doubt this is what you want.
Instead, I'm sure you'd want to match the perceived loudness to be the
same as before the correction. A tilt EQ is very unlikely to achieve
that, so manual gain correction will be needed in any case.
Hence, why bother with a tilt EQ?
I can see the appeal for DJs, but not for post production.

Around a centre frequency you reduce/gain the left/right side of the
frequency spectrum.
There's absolutely no need to know this for professional audio
engineering, this is for another target group.

Yes, a tilt EQ can be implemented in different ways, and perhaps the
most simple way is the cascade of low + high shelving EQ with the gain
control that moves in opposite way with respect to eachother. In fact,
at the moment I use this exact configuration.
Since I'm very lazy, I'm searchin for a plugin that does this with one
"tilt" knob instead of using two gains :)
I've to equalize some recordings that suffer of uneaven low/high
spectrum balance, and the "unbalancing" is different from recording to
another, so, one knob should speed up the eq processing.
Another way can be to automatically analyze each track, estimate the
"unbalancing" factor ad correct it using, for example, MATLAB/OCTAVE.
But the audio content of each track is not sufficiently representative
and very different from track to track, so a correction by ear is needed.
The first that comes to my mind is tilt EQ.
