Should I complain/send pics mentioning its been reconditioned (not included in description) and mentioning the rounded out bolts or am I being a touch sensitive?
If you really wanted to return it, you'd have no problem getting your money back based on the condition of the bolts. You need to decide if it's worth it though. If it was described as 'used' and this is the only issue and you didn't pay over the odds, you may be better off just keeping it.
Can the bolts be removed and replaced for decent ones?
If you're definitely going to need to get in there and the bolts are stuck fast, it may be better to return it and wait for another to turn up.
It's your call but I wouldn't say you're being sensitive.

I rode a 11 speed etap rim brake groupset for 20k kilometres and never had to touch the rear derailleur, other than to charge the battery and clean it.
