Hi there, we have 3 Land Cruisers in our family 2x Prado 120 ( one manual (mothers) and second automatic with air suspension- Uncles, both 2008.... and new 2022 150 Prado with 6MT Special and 2 batteries
without start stop stupidity 
We had 2 years or 3 somehing about problem with ac leakage on one LC 120..... maybe more years.... Very difficult to find leakage
one was under the car (Dual Air conditiion-front/rear,--- it was in the middle of car, underground O-ring was bad (small leakage).
But AC still leaked..... there was a massive leakage on one Top pipe..... We have been thinking another O-Rings???? nooooooo you need holy new pipe . That is not O-Ring problem, that´s a pipe micro holes in the pipe problem.
Pipe is this number..... there was a massive leak AC..... with no reason, and this pipe will everybone need I Am Sure
88716-6B501 This is the number of that massive leak pipe. Here are picrures....
https://partsouq.com/en/search/all?q=88716-6B501 At this part there is no problem with O-rings... but pipe has microscopic holes since 2008 till found 2020/2022 circa.
So You can be sure, that your leakage is right here....

somewhere under the battery.... that´s a leak goal.....
So there are 2 points under the car, if you have AC for rear passengers, there are 2 O-Rings, seems bad very bad after 14/13/12 years. And this Mega bad ass Leaking Pipe.
So I hope it will help. Pictures in the future.....
