bite the bullet on what?????

you can not repair the damage...

remove the worst leaves of a clump ... its almost time for the july reflush ...

and

START THE WAR .... many hundreds of posts and FAQ's about how to beat down the slimey enemy ....

brown curling leaf tips is a sign of lack of water.. you must be losing the other war.. in trying to drown your hosta... minimum one inch per week .. and more in july and august if nature doesnt provide such ....

ken

Any green on the leaves is feeding the plant....water, water and then some more.
you can't repair slug damage, only the plant can do that....and only with enough water so the leaves don't get crispy at the ends.

yep
leave them alone, but water them a lot

if you really want, give them a little fert to kick up the second flush
