Ludmilla is a Burst I SMG Defender who not only fulfills the role of a tank in the team, but on top of that can debuff enemies and buff allies.
What makes her great at tanking is that her taunt is combined with a self-buff that decreases the amount of damage she takes allowing her to shrug off more than half the damage the taunted enemies deal. In addition to her great tanking abilities, she can also lower the ATK and DEF of enemies she attacks with her S1 (although it's worth mentioning the debuff value is pretty low), and also she can buff the DEF of her allies with her Burst skill - which has only 20 seconds cooldown, but also DEF isn't really a good stat as it barely increases the team's survivability.
Still, be aware that when fighting with a big power deficit, Ludmilla will have issues surviving after she Taunts the whole screen for 15 seconds. While on an equal power level or a low deficit, she is a great tank, the bigger the power difference the worse she performs.
Also, to use her you are forced to play the 2-1-2 formation as without an offensive buffer (like Liter or N102) you will have a hard time clearing the stage within the time limit.

Has damage reduction to pair with taunt

20 Burst Skill Cooldown
ATK/DEF Debuff weakest among Burst I

her Burst skill is pretty underwhelming as DEF buffs aren't that good in the current damage formula
