I am attempting to create a custom component in multisim blue. I need the footprint of Texas Instruments component TPS61027DRC but it seems that the closest I can find in the program's database is a SOP50P490X110-1C generic footprint. Can I use the SOP50P490X110-1C footprint for the DRC package of the TPS61027DRC?

That footprint doesn't have any leads at all. You can just make one from a similar TI footprint (with fewer or more leads), or from scratch, which is not too difficult.
Thanks for the advice! I am making a custom footprint for it right now and I'm seeing two different drawings in the datasheet. One is titled Example Board Layout and the other is Example Stencil Design. Which one should I use for the footprint to send to my board house? Or does it depend on the board house's requirements?
Sometimes data sheets will refer to a manufactures drawing number as the basis for the footprint because there is no drawing specific to that part. For example switching regulator LT1614 datasheet indicates the package is based on LTC DWG # 05-08-1610. They didn't create a drawing specific to the 1614. Search that DWG number on their site and you get the official footprint for the device. As mentioned earlier in the thread however you should always print the PCB to scale and compare all pads to the actual component.
Use the board layout pattern, but carefully verify that it is correct for your part. The stencil is for applying solder paste.
There are quite a number of different footprints available for this part. You need to have the complete part number,
which includes the specific package type.
See addendum page 1 in this data sheet for the range of packages, and the corresponding part numbers.
