Ran across these wheels on Ebay. Sounds like a nice set of wheels with a dynamo hub in the front. The seller is being honest about the condition and posted a video showing two slight dings in the rear rim. Can I expect this to cause issues and just pass on it?

It can cause both braking and maybe tire fit issues. It also may not. There is no way to know until you try them. Do you feel lucky? Roger
Well...better the rear than the front...

If it is a common rim and the price is good enough, buy the wheels, get a replacement rim, and just move from one rim to another. My first "wheel build" was that kind of situation- the rear wheel on my hybrid had a bad rim but everything else about it was great. I bought a new rim, taped it to the other one, and just removed the spokes one at a time and put them into the new rim, then trued it up. You can borrow my truing stand and tensiometer.
Or... just bend it back with pliers.

$99 + shipping This is for the Schwinn Crosscut frame I just bought.

Bang it back flat, with A hardwood dowel punch so it won't leave a mark, like Pliers might..

The $99 + shipping is for the wheelset? How much for a replacement rim? (Come on, you know you want to build one.)
If the price is $99 for the whole wheelset.... BUY IT NOW. Even if the whole rear wheel is a throw-away, a front wheel with a dynohub is worth that much.

That's what I needed to know, thanks.

I've used two small crescent wrenches and popsicle sticks to remove tacos like that before, with mixed success. or a anvil with a piece of hardwood over it, and a hardwood dowel as a drift with a small hammer, and someone to hold the wheel for you. tap gently and work slowly.

I bought them. 32 hole deore hubs with a front dyno, Specialized branded Alex rims. Would have preferred 36 hole, but my road bike with 32 hole rims went for 12 years before it had any problems. Worst that can happen is I'll have to get new wheels built around the hubs. Thanks for the feedback.

I'll add that I dinged my front rim like that last May and never got it to where I'd consider it "good" even though I rode another couple thousand miles on it... and in a fit of "why didn't I do this earlier" I bought a replacement rim from Easton for a measly $65 or so and it arrived today. I'm willing to bet you can find a replacement as well, and if it's the same rim you can even reuse the same spokes etc.
Mine worked fine though for all that time but pulsing front brakes on a mountain descent... not so fun.
No big deal, IMO an adjustable wrench is a good tool to tweak it straight, works a treat.
But err on the side of narrower than wider, it makes less of a pulse in the brake.
Weigh your decision against a hand built wheel with dynamo hub like this:
