L1B and I-94 expiring in march

I am working for a US based MNC and I have L1B and I-94 both expring in March. Can I still come back to US in April on anyother visa to work till I get my H1 in October. My employer is applying for my H-1.

Only work visas are H-1 and L-1. You cannot come on H-1 as it’s start date will be Oct 1. You can come on L-1 but only if L-1 employer is willing to file for extension.
