After some very weak search fu, I have turned up nothing. I am creating a Paladin who uses Desna's Shooting star but Starknives do a pitiful 1d4 dmg. I'm considering using an effortless lace to negate the penalty of using a large starknife but there lies the problem.
Do large light weapons become one handed weapons or two handed weapons. I assume that it'd become a two handed weapon but I'm curious because two handing a starknife would be goofy and I don't think that I can add Cha and 1/2 to the damage.
Srd says, "If a weapon’s designation would be changed to something other than light, one-handed, or two-handed by this alteration, the creature can’t wield the weapon at all" I don't fully understand this statement. Are large light weapons too unwieldy? I get that 2500gp for 1.5 more average damage is crazy but I'm a crazy guy.

Large light weapons would be one handed and huge light weapons would be two handed for a medium creature. The line you quoted was refering to the fact that you couldn't wield a gargantuan starknife at all as it would be above a two handed weapon (you also couldn't wield a small starknife as that would be below a light weapon for a medium creature).
I'm not sure about adding 1.5 cha to damage if you wield a large or huge starknife two handed. My guess would be yes, but I'd ask your GM if no one else can give you a definitive ruling.

I'm not sure what the proper etiquette is for nercoing your own thread but I still have questions. Is a large one-handed weapon still a one-handed weapon for class abilities like for Swashbuckler's panache? Is a small two-handed weapon a one-handed weapon for Swashbuckler? I'm trying to expand swashbuckler's weapon list here. A swashbuckler can swash buckle with a morningstar but he could increase his damage if this was legal. With the effortless lace, most swashbuckler weapons can have their damage upgraded the only problem being swashbuckler losing his Precise Strike.
But if a character took a dip into Swashbuckler for the deeds, could he regain panache with a large battleaxe? I was looking into creating the Lawbringer from For Honor and he's a counter attacker with a poleaxe. Being able to parry with a two-handed weapon would be pretty cool and not too toonish. The average damage only goes up by two (4.5 to 6.5) while a swashbuckler with a normal sized weapon does not have to worry about size penalties and gets his level to damage which is already one more damage by the time he gets it. Of course, two handing a large battleaxe would add 1.5 str for more damage but Precise Strike can keep up (1d8 +dex +level vs 2d6 +1.5 str). So this would be cool if it works but not necessarily powerful. A paladin who dips into Swash would get more utility out of this little trick than actual swashbucklers.

No

Yes
Bladed Brush with the glaive might be what you are looking for. A fauchard is described as being "like a glaive". A permissive GM might allow Bladed Brush to work with a fauchard, but it wouldn't work RAW.
With the Whirling Dervish archetype you can get 1.5x dex to damage as well.
