2FA has become the standard is an absolute must for any crypto exchange, and as you mention, an integral part of LiteBit's security. As you also mention, they've been around for a long time (in crypto terms) and I can vouch from personal experience that I have never seen anything that would make me doubt their professionalism and competence. I've accumulated on both the buy and sell side, and everything's always worked just as designed, for me anyway.
