The value of Learning Cost was based on an Integer type which meant it can have a maximum value of: 2^(31)-1. So with that being said you'd have to go over that max point in the amount of learning points needed. The LP cost formula is something like :

(assuming we start from said stat == 1; n == number of times ticks you put into that skill)
From that the actual value you'll need to break the Integer maximum for Learning Cost is around 6500ish, i forget the exact number.
All of this is fixed now though so learning skills that cost negative lp doesn't work and even looping through stat increments until the cost is within your current lp range(something like 1700000 @ 150lp, again i forget the exact number) doesn't work

.
Also note: you don't need to sit there and click repeatedly all day or scroll repeatedly to achieve such numbers when you can just write in tiny scripts that are ran when a button is clicked while ingame to do it for you
ie:
(ignore the stats and everything,i was just playing around.) But for an example someone could make say the "Neg" button run through 6500 iterations of incrementing a single stat in a very very short period of time (less than 10 seconds) and then simply just hit buy .
