I disagree with your summary of use of WordPress as it is not used on any of my VM. I detest it, or rather its add-ons, So my requirement for litespeed is zero.
But I do know many users here use Apache (I moved to Nginx years ago) and are tied to WP. So I do understand your request and that WP is dictating it.
However this has been asked for before and I think comprehensively answered. I doubt if anything has changed
