Plenty of races that give stuff to wisdom. Of course, I don't think that there are any non-core +0 LA races that give bonuses to wisdom.
What you can do:
Ask your DM to house rule a feat that gives alternate ability spellcasting
Theres the Aasimar, Doppelganger, Githzerai, Kuo-Toa, Mindflayer, and Pixie in the MM
Wild Gnomes (not sure where thats from)
There's probably a bunch more, but that's all I found now. All of the above have varying amounts of LA.
