You haven't yet mentioned the type of LCD which was used....
Anyway, do you still have it and are able to match up the connector on the LCD, to the PCB?
It appears you have removed a bunch of components from the left side of the bottom pic...what did you remove?
Was the header "Cont5" removed by yourself and could it possibly match the pin count of the LCD connector?
What about "Cont3"? EDIT: Just noticed the above additional text.
If you can find out which header the LCD was originally connected to, you could follow the traces back to an IC and do a search for a datasheet for that IC.
But, you will likely find out that most of the remaining IC's on that board are of little use to you right now though....
You'd probably be far better off starting from scratch and using Nigel's tried & tested tutorials, rather than trying to scavenge an LCD controller IC and then work out how to interface a PIC to it - you can control an LCD from a PIC quite easily....
Identify the LCD module that you have already removed, and hope it is HD44780 compatible.
If it is, look here:
for the lessons,
and here:
for the hardware.
If your LCD is not HD44780 compatible, set it aside and get one which is. They are not expensive and the lessons learned from Nigel's pages will give you a good start with PIC's.
TBH, I'd just strip both those boards bare and toss 'em, saving the components for later projects.
HTH.
