I recently completed a Zig Zag chair. The plans called for 1 1/4” x 1 3/4” x 18”-24” long white oak. The only white oak I had was some 3/4” tongue/groove flooring, with the 3 ridges on the bottom. I planed the boards down to 5/8” thick, biscuited them in 4 places in each board and glued them with Titebond III glue, opposing the grain the best I could.
My question is this: are my 2 pc laminated boards weaker or stronger than a solid pc 1 1/4” thick”

Assuming a tightly clamped glue-up, they should be stronger. The glue bond is stronger than the wood itself. If you were able to break that piece apart, the wood would break before the glue would give.

There really shouldn’t be any difference as long as the glue bond is good.
