If you use ublock (or adblock, or adguard, or anything else that uses EasyList syntax), you can add a custom rule
lesswrong.com##.NamesAttachedReactionsCommentBottom-footerReactionsRow lesswrong.com##.InlineReactHoverableHighlight-highlight:remove-class(InlineReactHoverableHighlight-highlight)
which will remove the reaction section underneath comments and the highlights corresponding to those reactions.
The former of these you can also do through the element picker.
