Did we build and send Russia any of those T34 tanks as part of lend lease against the Germans in WW2?

Russians built those on their own. Lend-Lease may have helped with the production.

In fact, a German general who saw the T-34 for the first time, remarked that if the Soviets could mass produce it, Germany would lose the war, and this was when the Germans were already halfway to Moscow.

They defaulted on their Lend Lease bill.

The short answer is “no”, but we did send them resources and materials that facilitated their tank production. We also sent American trucks and tanks. The Russians generally liked the M4 Sherman, assigning them to Red Army ‘Guards’ formations.

We did supply them with some Sherman tanks, but Russia had its own steel manufacturing and tank factories in WWII. When Hitler invaded Russia, Stalin had them dismantled and moved them by rail nearer to the Urals. We also sent them train engines and perhaps rail cars. Here's an article about the military machinery that Britain and the U.S. supplied to Russia:
