Many casinos do offer bonuses for live casino games, whether it is called a welcome bonus or deposit bonus. However, not every online casino has a welcome bonus for live dealer games specifically. Welcome bonuses are usually deposit or no-deposit, meaning you have to drop a certain amount into your account to get the bonus money. You can then use the bonus money on any games you want, including live dealer casino. Casino bonuses have wagering requirements anyway, so you will have to use the bonus money to bet on a game a certain amount of times. Always read the wagering requirements for a bonus before you accept that promotion.
