Q: (L) And since the Little Ice Age lasted from 1450 to 1850, that was the period of its generalized influence?

A: Yes

Q: (L) So that suggests that it takes like 400 years for something like that to pass through the Oort cloud?

A: Yes

Not sure I understand this part. Why would the closest approach taking 400 years imply that the brown dwarf would also be only 400 years in the Oort Cloud?

The Oort Cloud is enormous and the brown dwarf will slow down a lot in that part of its orbit of millions of years.

Maybe it needs only 400 years to pass through the Kuiper Belt which is much closer and much, much smaller. Or did Laura mean 400 years to pass through the inner solar system, not the Oort Cloud?
