The Pro Mini does not appear to have any screw holes. How to you go about mounting it in the final project?

Duct tape. Hot melt glue. Nails. Cotton balls. Whatever works.
What does your project look like?
Board, Perfboard, Proto-board, solderless breadboard or what ever?
My standard flippant answer would be chewing gum or double sided foam tape 
More serious, my next project is using a Pro-Mini - I have male headers to the back side, the finished project will have matching female headers on the circuit board and I will plug the Pro-Mini into the headers, if I get bored with the project or it is no longer relevant I will just unplug the Pro-Mini and move it to the next project
I am using a solderless breadboard for the test project now, works nice with the male headers on the back side
The project is very simple so I don't have a lot to attach it to. I haven't surveyed the pin out of a parallel LCD versus Pro Mini. I hope I can attach them via soldered headers, but I'm afraid the pin functions won't line up.
The holes at the end don't, but that may not matter. They typically come with a pair of male headers for the sides and a bent six pin for programming. I am going to replace the latter with a straight one to keep the pins out of the way. If you have the confidence, you could save on the headers and simply solder it in directly. There is a quite nice 24x30 solder perfboard on eBay, dirt cheap. As I understand it, a Pro Mini is essentially a stripped down Uno, so, if a Uno can drive the LCD, so can Pro Mini, but you might need to ensure the voltages are right.
Header or machined pins to a mother board or mounting board the same size.

I'm not worried about the drive. I was speaking about wiring (soldering) the Mini direct;y to the LCD.
Sounds like a great idea. Everything you need to know is in reply #1. Good luck.
I bought a screw shield and mounted that to my enclosure. I like the screw terminals.

A screw shield for the Pro Mini?
I bought a bunch of different screw shieldshield to see which I liked. I thought I bought some for the pro mini but maybe I am thinking of the nano. Take a look at electronics salon on ebay.
I made custom PCBs for use with Arduino Pro Mini's, where you can either connect it with pin header, or solder the Pro Mini directly onto the PCB.
They're available from my Tindie shop here: https://www.tindie.com/products/DrAzzy/project-board-for-arduino-pro-mini-/

Arduino Pro mini undershield
The screw headers would not solve my problem. The undershield might, it looks like there are two mounting holes. Are they your design or are they available on the market (Amazon, eBay, etc. what should I be searching for?).

So far I have been only using I2C LCD units. I have not driven any parallel. It appears there only 6 pins required for parallel mode. Has anyone directly soldered (using header pins) a Pro Mini to an LCD? Any chance of a pic?
I was thinking if they are directly soldered, I can use the LCD mounting holes to mount the daughter pair.

I've been wondering this myself as many of the Arduinos and breakout boards have very small or nonexistent mounting holes. What do you think of this?

A piece of regular perfboard would work just as well, but you'd haveto do a little more soldering to connect things. Perfboard also has mounting holes in the corners.
