First of all : is the aircraft dispatched with the LE FLAP TRANSIT LIGHT INOP and/or one of the overhead indication light INOP ?
Leading Edge Flap Transit NN CKLIST.
-> If the trailing edge flaps are UP : Airspeed 230 MAX
Then the checklist asks about roll. The point here (I think) is understanding if you have roll or not
Easy in smooth air, maybe not so in moderate turbulence. In the example you gave, you mention one slat extended. Therefore if you have roll, you must fly 230 kts , set Vref 15 +5, etc..
No roll, and the light is still on (LE FLAP TRANSIT) with one LE device extended, you may fly 300/.65.
If the aircraft is dispatched with some faulty light indications, you simply follow on ground the operational DDPG procedure according to that.
