Thanks for reaching out to us about this! Officially, you can license LabVIEW for FRC on up to 20 computers, provided that those computers are used exclusively for FRC purposes. I've linked a thread below that goes into more detail on this. Let me know if you have any further questions!
(also, as a side note: any response you see on the forums where the username has the blue NI logo above it means that response was posted by an NI employee with an @ni.com email address, so you can be sure they're legitimate)
