I don't know of any strictly WWl battle cruisers but the following can be back dated, HMS Hood and HMS Renown. These ships were designed and built under WW1 building programs and were the last of the periods battle cruisers.
I think that there is an HMS Iron Duke kit and HMS Warspite is from that period.
HMS Campbelltown is a USN destroyer (Can't remember her original name).
Any of the Vand Ws, White ensign, will do for the RN.
ON the other side SMS Emden and a torpedoe boat are available.
An Australian company has/is about to produce a submarine AE2.
