Welcome to the world of LFS.  You will learn a lot.

It shouldn't be a problem.  /tools/lib/*strip won't match anything.
Depending on the way the strip program works, you;e either strip the
unneeded symbols or all symbols out of /tools/{,s}bin/*.  You knwo what
that expands to, right?

In any case, nothing is hurt as long as you don't strip all symbols out
of libraries (removing debug symbols for libs is OK) and it doesn't look
like you did.

You're getting carried away here.  The grep worked as designed.  You got
the succeeded messages.  The other output is just a side effect.  It
doesn't say you will *only* get the succeeded messages.  In fact you got
exatcly four lines.  The first line happens to be very long and wraps.

Note that we are matching  /usr/lib ... crt[1in] ... and the first line
matches too.

Keep going.  You are doing fine.
