I saw in a couple of brachos charts that the Bracha on banana chips is bore pri hoadamah. Shouldn’t the Bracha be shehakol, because bananas are normally eaten raw ?
Correct, they are usually eaten raw. The reason the poskim say to make hoadomo in them is because there are a lot of banana chips and it is eaten enough that it is also considered the norm to eat them after being baked.
