I bought I Lavatera Barnsley plant at the weekend because on the label
it said suitable for all soil types, perfect for my waterlogged garden I
thought I have since read they prefer well drained soil, will it be ok
and eventualy grow big enough to absorb the water or will it die?

You've mistaken what "soil type" refers to.

"Soil type" is normally taken to mean soil structure and chemistry;
whether it's acid, alkaline or neutral; chalky or peaty, sandy or clay.

It doesn't refer to the plant's preferred aspect ( sunny/shady, well
drained or boggy, wind tolerant or sheltered).

Your lavatera won't thrive (or even survive) in waterlogged soil.
