In the event GP doesn't respond, I probably have the same unsatisfactory answer that the Q&A from the link does: we don't yet know. I too, have the same interest regarding insulin spikes from artificial sweeteners and spent considerable time researching. Caveat, this was about five years ago so there could be new findings. While the research is inconclusive, I personally try to cut down on artificial sweeteners. I suspect they can cause an insulin response. This is based on my understanding of the literature and my n=1 experiments.
