Hi,
Once you play your rosbag file you can subscribe to the topics for example /odom /scan /tf in your case and save the desired data in file. you have to go through these tutorials to see how to subscribe any topic rest is writing to a file.
I dont have any experience with Ros toolkit for Labview. What i understand that you have laser scan in odometry in Lab view and you want to run gmapping on that data.

Edit 1:
Yes its possible to get the map data. you can see Map message here and figure how it looks from inside. Each time this message get publishes the size of data is 16MB. you can reduce the size of data by altering the size of environment in Slamgmapping code. you can subscribe to the /map Topic and store that data and feed it to Labview.
