It looks like there's some precedent for workarounds that FDR used to aid the UK when Isolationists didn't want to help during WWII, and that Biden has already been doing a good chunk of it. Without direct cash, I do think there are fewer options, but I'm curious what will happen if an aid package isn't passed by Congress in early 2024 once the current one runs out.
Politico: The WWII Strategy Biden Can Use to Bypass Republicans on Ukraine
Roosevelt’s effort to arm Britain ran the gamut from outright executive fiat (bases for destroyers, surplus transfers) to skillful negotiation with Congress (cash and carry, lend-lease). But there was a common thread running through these maneuvers: The United States never appropriated direct military assistance to the United Kingdom. It traded stuff for stuff. Allowed the British military to buy war materiel from private manufacturers and transport it on British ships. Offloaded “surplus” goods.

Biden faces a similar set of circumstances. To sustain America’s support of Ukraine, he will need to find creative ways to bypass the handful of GOP congressmen who currently enjoy functional control of the House. He already enjoys some leeway. Last year, he signed into law a latter-day version of the Lend Lease Act, patterned after the original law, that allows him to lease military equipment to Ukraine on a five-year basis. He might also look for ways to use NATO or other allies as a middleman in the transfer of arms.
Israel received $3.18B in FY 2022 compared to $11.8B for Ukraine.

It'll be interesting to see what that chart looks like for 2023 and 2024. And hopefully there's less genocide all around, eh?
