I currently have 225/55R17 tires on my 2007 LT. I can get a very good deal on 4 215/55R17's. Can I put these on the current stock rims? Pro's, cons? Not a car guy, so any input is welcome. Thanks.
That's totally fine. It only comes out a hair shorter - just over 1/4", so your speedometer will be off about 1 mph at 60. Basically inconsequential - you wont notice any difference between the two.

Lol I spent way too much time trying to figure out what I wasnt understanding.. Hopefully this post does the same for you

Im not following what you mean, can you explain? I re-read the question and what Id written and I dont see any inaccuracy. I guess the math on total height delta could be argued to be a little closer to 1/2" than 1/4", but bottom line is its a negligible difference.

The difference between the tires is width. 215 vs 225

Right, and because the second number / profile is a percentage of that width, the overall tire will also be a different height because the widths are not the same. Thats why Im confused what youre getting at...
Here's an explanation of the second number from Michelin:
The second number is the relationship between a tire’s sidewall height and the tire's width. It is expressed as a percentage. For example, 55 indicates that the sidewall height, between the top of the tread and the rim, is 55% of the tire width.
So the wider tire will have about 4.9" from the rim to the outer part of the tread whereas the narrower tire will only have about 4.7" (both rounded off of course). So that makes the overall tire height top to bottom about 0.4" different in total.

A bit more evidence if you dont believe me - tire specs for the exact same tire in the two sizes the OP mentioned. Notice the revs per mile is higher on the 215, thats because the 55% sidewall height is based on a narrower width, so the overall tire is a pinch shorter and needs to rotate a few more times to cover a mile.
