A space is missing in your command after -l, you wrote:
otool -l/Applications/OTB-7.2.0-Darwin64/bin/otbApplicationLauncherCommandLine
You should not move the OTB installation directory after its extraction, because the rpath is hardcoded in the executables. If you want to install otb in /Applications, you should use the target option when extracting the archive:
chmod +x ./OTB-7.2.0-Darwin64.run
./OTB-7.2.0-Darwin64.run --target /Applications/OTB-7.2.0-Darwin64
