First and foremost; AO & AO critcss power-up can help improve your GPSI results (which tries to quantify how well you follow performance best practices, but which does not reflect the actual performance), but it’s not their primary aim.
Secondly; there is no paying version of AO. There are paid for configuration/ performance tuning services, but these use exactly the same versions of AO & AO CCSS 🙂
Now based on your GPSI results, your most important issue is with “server response time”, for which you’ll need to implement some kind of page caching (you’re on litespeed, but given the server response times it seems not to be caching).
2nd important issue; GPSI flags 4 images that are not sized correctly (i.e. the image file used is bigger then the resolution it’s shown in). Change that manually or consider using the (shortpixel-based) image optimization feature in Autoptimize.
Next up; your CSS is not render blocking any more (that’s AO CCSS’s job) but you still have one render-blocking resource; jquery.js. You could try to remove that from AO’s JS optimization exclusion list, you could try asyncing it or you could try the “defer jQuery” advanced option in AO CCSS advanced options. If you’re unluck neither of those will work, in which case you would have to re-developer your site to make sure no plugin/ theme JS expects (needs) jQuery early.
Happy optimizing!

hi,
There is only one page is listed in AO CCSS’s job

Based on the HTML source of e.g. https://www.egtours.com/location/paro/ Autoptimize is not active Chitrag;

If I remember correctly you’ve had similar issues earlier, where for some reason sometimes Autoptimize seemed not active, and sometimes active without “inline & defer” active. Did you make any progress in identifying what is the root cause for that strange behavior?
