I recently spoke with someone from Alpha Bridge Ventures (https://www.alphabridge.vc) after writing a book about entrepreneur mental health. They provide mental health services to their founders, and my understanding is that they have a firewall between the investors and a separate entity that provides mental health services. A menu of mental health services is available to founders but the investors never know which founders are using them. Although they emphasize the intrinsic humanitarian value in helping their founders, they also rationalize their approach by noting that providing mental health services is good business; founder burnout is a leading risk factor for startup failure. I was impressed by their approach, which seems to mitigate the incentive problem.
