Let's get this rolling!
It seems to me that Olvi titles could easily fall into a few categories.
Age: Include all the of the current age titles if they apply to the character and add some for fun.
Smoking: All of the smoking teaching titles and more for fun.
Food: We are a little food-centric, eight meals a day plus snacks so I think we might have something to work with.
Farming/Homebodies: Since we are seen as a cheery, family loving, partying sort of people, we can work with the wholesome, close to the earth, cheery gardeners, farmers, drinkers, etc.
The Dark Side: Yes we are clever and maybe a little sneaky too, just not really malicious. Tarts, Rascals and Scarpers feel free to speak up.
The Feets: I'm proud of my feet, you are proud of yours? It could work.
Some of the ones that came to mind:
Age: All of the current age titles - These others could relate as much to personality as age - Biddy, Coot, Beldam, Dowager, Old Fogy, Old Maid, Gramps, Granny, Geezer, Lassie, Damsel, Half-pint, Shaver, Nipper, Lass, Moppet, Gaffer, Greybeard, Nana, Spinster, Goodwife, Bachelor, Missus, Missy, Goody, Widow, Widower, Curmudgeon, Chickadee
Smoking: All of the smoking titles, Puffer, Wheezer, Leafroller, Tobacconist, (a real smoker might be more inspired)
Food: Gormand, Noddy, Larder
Social side/homebodies/earthy:
Cropper, Gleaner, Homesteader, Bucolic, Mossback, Stubble-Jumper, Homebody, Butterfly, Lark, Larker, Cupcake, Tootsie, Clodhopper, Cob, Gardener, Hayseed, Buckwheater, Goat-girl/boy, Shepherd, Herder
The others:
Tart, Sweettart, Sourtart, Spitfire, Quipster, Wag, Irascible, Fleetfoot, Banterer, Card, Japer, Wisecracker, Teatotaler, Nag, Fussbudget, Fusspot, Buck, Chap, Gamin, Tomcat, Wooer, Loony, Kidder, Punster, Zany, Rowdy
(I am sure we could work on the sense of entitlement that many olvi have. After all, everything is actually ours anyway, and we don't mind sharing, you don't really mind sharing, do you?)
We could do these in whatever our language is too.
