Taking a car in for a 'once over' for 'bolts and nuts' is not quite the same as 'for an alignment'.
Also, any install/build/work that would NOT include adding fluid/lubrication is a Red Flag presaging many problems to come, some of them surely dangerous and/or harmful to you. In this instance, maybe just expensive.
You are 100% correct about that.
I have been doing my own wrench work for decades. What I've found wrong that has been written (by folks that should know the correct process/method/procedure) FAR surpasses what I've read that is correct. It is also true that I could regale you with stories for HOURS about disastrous work done by ASE certified mechs. How about a replacement of a fusable link with a hunk of wire that later, when the steering column movement caused a second short, the car caught fire with my wife and kid in the car? Totaled the car.
If you didn't care for my earlier post, I guess it's a good thing I edited a whole lot of the 'colorful' out of it. ;)
Good luck on 'ya. Enjoy your new ride!
