The only Hireling i can find that's close to what you're referring is the Gnome Hireling, which allows you to have a second Big Item. That Big Item would have to be dealt with just like it explains in the base rules about how to handle getting rid of extra Big Items if you lose your Dwarf Race.

For what it's worth, you can carry (i.e., have in play) any number of small Items.

Using the Elf Hireling as an example: It can use for you any one Item an Elf can use. That means Items that do not have a Class or Race requirement, Items that are usable by Elf only, but not Items that say they are not usable by Elf, and not Items that say they are usable only by some other Class or Race.
