"Is the Blast Off animation obtainable by Random Brew or do you need to buy it?"

There was an issue with it not being obtainable, but that was resolved very recently in Version 2.2.2.

"Fixed an issue where the Blast Off death animation wasn't showing correctly as a legendary item for the legendary Cauldron brew. "

If not,then can you get TP from Random Brews?

You can, but it's extremely unlikely unless you basically own every item and 3 of every scroll. Those who had pledged $250+ USD to any of the three Kickstarters have unlimited Town Points, so they're more likely to get Town Points as a prize if they went ahead to buy everything.
