What Buddha or bodhisattva should be invited to the haunted house in town to ward off evil spirits?

The so-called "haunted house" or "exorcism" is purely superstitious, and Buddhism does not talk about it. Since you want me to answer, I'll say a little, don't take it amiss, maybe it will ease your fear.

Generally speaking, what the family gives most is Guanyin Bodhisattva or Tibetan King Bodhisattva or the Three Sages of the West. In Buddhism, people who can recite Buddhist names or scriptures will be blessed by the Buddha and the dharma protector. Therefore, it depends on which Buddha and Bodhisattva you are destined to be. Please invite that one, and then recite the Buddha's name frequently, and you will be blessed by the Buddha and Bodhisattva and be healthy physically and mentally.

If you are destined to recite the Tibetan scriptures and turn over your unjust relatives, creditors and three evil beings, your home will be absolutely safe and full of life. Good luck! Amitabha!
