Is it okay that my Sony TV power cord replacement has a slot for a third prong that the original doesn't?
The OEM cable does not have a ground or earth connection.
The cable on the right does.
So this will be a safe replacement for the original cable.
The ground connection will not be used and that wire ...

Absolutely no problem.
The screws (actually called "lag bolts") bite into the wood immediately around them, and the wood fibers around that hold the bolt in place.

How safe is it to mount a TV tight to the wall with steel studs?
If the TV will be on a pivot arm the answer is absolutely not. If it will be tight to the wall, as you say, and generally nobody will be physically handling the TV (tilting or moving, e.g. to plug in ...

How do we add structurally sound faux stud for a single stud TV mount?
A bunch of ways to do this. What I would probably do myself, which is not what you are currently planning, is:
Cut a piece of plywood, probably 3/4" thick, 24" tall by ~ 20" (studs 16" apart) or ~ 28"...

3/4" plywood is very strong, and if you use a sheet of sufficient size will provide very good support. Assuming 16" stud centers I suggest about 52"w by 16"h. This will give ...
