Why is this domain getting type in traffic ?

Probably fat finger typos aiming for itau bank in Latin America.

99% is what ecalc said but you can easily find out by checking the origin of the traffic (there is a tab in voodoo's interface for that), switch to that country via a vpn and type the domain's keyword in google. Chances are you're going to get your answer there.
Alternatively, there are some tools that can search from a different location without using a vpn

Just try monetize it and settle for an income.

How long have you owned it for, and did you check the history before buying it? And what kind of "numbers" are you talking about - thousands a month?

If so, then type-in traffic is virtually dead (with non-words like this) in numbers like that, and it's more likely that "itaui " has backlinks from a previous owner.
