There is a walkthrough mod on the first page which is an in-game tool that displays every event available at a single time, and the hints/requirements to them. No one should play without it tbh. Always make sure to take a look at the hints tab begore engaging the following event.
The AutoVN isn't optimal as it is a tool for those that simply can't stand the nature of the game. The thing is, the game is meant for you to play it, and even though the AutoVN may try it's best, things will always be lost by forcing LiL to be a VN. It really should be a last resort for people that just can't stand LiL and wouldn't play it otherwise.
Lastly, there is a puzzle guide, also on the first page. On every chapter os the game there will be at least two puzzles during special events. These are not covered by the walkthrough mod, and you should consult the spreadsheet (puzzle guide) when it happens.
For anything else, you can consult us. If asking about a specific event, inform its name, or at the very least what's happening/who's saying what, so that we can identify it and troubleshoot.
There is also a useful tool called URM, that I recommend you install. It isn't needed, but it will inform you of variations during the events, and enable you to change some variables instead of grinding later on.
