What is your OS? There are steps on how to uninstall the legato on the Oracle installation manual. Choose the appropriate installation and follow the steps to uninstall.

Seconsly as far as I know, in the solaris installation, it would get executed under root.sh script, which you would be executing at the end of the oracle installation. There one option would ask whether you would like to create the legato.

The manual explains every thing clearly. Follow that to install or unstall your legato.
