The GIF format requires that pixel data be stored as an LZW stream; there
is no option to specify any other encoding.  However, it is possible for a
encoder that doesn't use the LZW algorithm to produce inefficient but
valid LZW streams.  I'd not heard of RLE GIFs, but I suppose you could
make an RLE encoder generate an LZW stream.  A web search turned up
references to several tools that do that.

Any phone should be able to cope with a GIF that wasn't produced by a true
LZW encoder, because it's in exactly the same format.
