I suspect -lpthread needs to be added to sendmail compile, but not sure how

With all due respect, I'm not sure there is really a problem with this.
I've installed sendmail-8.13.1 more than once on a LFS-6.0 system without
any of the problems you're describing.

Did you follow the BLFS instructions for installing DB? There is special
instructions there to ensure pthread is link properly. You will need to
follow the SVN DB instructions to see the pthread stuff.
