Hey aspirant,
It is very difficult for you to get admission in any colleges through your IPU LEET rank for CSE. It would have been helpful if you would have mentioned your category.
Nevertheless, the last year's cut off by rank for the last round of counselling for CSE closed at a much lesser rank for General All India Category candidates, for almost all the colleges. If you would have ranked within 500-600 then your chances would have been more.
Even if you belong to any reserved category (SC/ST) then also it is difficult for you to get B.Tech CSE of B.Tech CSE lateral in most if the colleges.
You can check this cut off list from the official Website of ipu leet :-

Hope this helps,
All the best!
