If I have a lawnmower, backpack leaf blower and snow blower, is it OK to share two 7.5Ah batteries between the three tools?

Of course. You're unlikely to be using all three tools at once!

True. My question was more aimed at whether this will cause my batteries to wear out faster. Is it more economical to buy the extra batteries now even though I have enough by sharing?

Well, batteries have a limited number of cycles, so technically the more you use them the sooner they will run out.  But I would not buy more now to make them last longer unless you are getting some kind of a discount thru a kit purchase.

 Otherwise, technology improves and gets cheaper, so might as well use up your 2 batteries (assuming you use them enough to actually wear them out - possibly won't happen) and purchase replacements in the future.

Scott, hopefully replacement batteries will have dropped in price by the time you'll need them. With many hundreds, if not thousands, of cycles worth of expected life I'd think you will be good for a long time with two 7.5Ah batteries.
