In the latest version 1.0.6 it says it does, but doesn't:
$ otool -l linkedin-sdk | grep '__bitcode'
Produces no output.
Until LinkedIn update their SDK, the only solution is to disable bitcode. Build settings > Enable Bitcode to no.
LinkedIn recently released v1.0.7 of their iOS SDK, which corrects an earlier issue in v1.0.6 with bitcode support. Note that it is only available on the arm-64 architecture, so the correct command-line test would be
otool -arch arm64 -l linkedin-sdk | grep '__bitcode'
