will this fit a kohler k-7548-4 faucet?

If you can get yours out—take it to a home improvement store and see if they have one. It’s nearly impossible to guess. I had to buy a kit at Amazon that had the blue faucet key. Lowes—where I bought my faucet—didn’t even have a key to remove the filter. The key set I bought was—JQK Cache Faucet Aerator Key for M 16.5, 18.5, 21.5, 22.5, 24. The kit was $7.99 and had a nice range of sizes.

Does this come with the key?

Yes, the blue handle shown in the photo is used for installation or removal.

Will it fit model 19950-dst?

The absolute best way to know if this is a suitable replacement is to remove the old part and measure with calipers or even a micrometer as shown in the seller's product description. The dimensions should come close to the product description from where you're buying the replacement part.
