The whole vegan thing has never made sense to me, so I've never read too much of their stuff. But one criticism I've seen of HCLF is that the improvements those diets make to HbA1c are positively miniscule. Just comparing the results of Barnard's studies to those of Virta where massive changes are achieved, I wouldn't bother. OTOH, vegetarian versions of LCHF can also have beneficial effects. I know there are versions of LCHF vegan, but that would be a very complex diet for a non-professional to figure out for themselves.
The vegan proponents also tend to 'confuse' (hard to believe it's not deliberate) physiological insulin resistance, which is a perfectly normal response to LCHF, with hepatic insulin resistance which the main driver of Type 2 diabetes:
