Not so common but you can get VFDs that go from ordinary single-phase mains to high-voltage three-phase. Not ideal because it's 380V rather than 440 but I found this example on Amazon UK. I think a more serious search would find 440V units.
As VFDs operate internally at low RF frequencies, the transformers needed to achieve voltage step ups at high power are cheap and tiny compared with conventional power transformers. A 50Hz transformer doing the same job would be physically bigger than the VFD and cost far more than the electronics.
The advantage of these units is removing the need to disembowel an inflexibly wired motor to find the star point. The disadvantage is they don't have a track record: are they reliable? I don't know. A pessimist would point out high voltages tend to reduce reliability, an optimist would refer to the huge improvements in high-voltage semiconductor technology made over the last 50 years. I'm inclined to be optmistic – VFDs aren't chock full of OC71s or any of the other 'three-legged fuses' of my youth.
