As I understand that you are looking for the lens profile for your Canon EF 11-24 f/4L USM. Lightroom does offer this lens profile in Lightroom CC 2015.0/6.0 version, which is the next version of Lightroom 5. Therefore you need to upgrade your Lightroom software.
Otherwise, you can create own lens profile: Work with lens profiles in Adobe Photoshop, Lightroom, and Camera Raw
Also, you can refer link to know what other lens profile supported in which versions of Lightroom: Supported lenses
